PASCAL Tree Planting Issues, Tree Planting Issues

It's not a problem that pascal can solve, it's not a panacea!!

1. If trees are to be planted at both ends of the tree planting line, then the number of trees planted should be 1 more than the number of sections to be divided, that is: the number of trees = the number of intervals + 1.

2. If there is only one end of the tree planting line to be planted, then the number of trees to be planted is equal to the number of sections to be divided, that is: the number of trees = the number of intervals.

3. If no trees are planted at both ends of the tree planting line, then the number of trees planted is 1 less than the number of sections to be divided, that is: the number of trees = the number of intervals 1. ~

4. If trees are planted on both sides and at both ends of the tree planting route, then the number of trees planted should be 1 more than the number of sections to be divided, and then multiplied by two, that is: one tree = number of sections + 1 and then multiplied by two.

2. Plant trees on the closed line, and the number of trees is equal to the number of sections, that is: the number of trees = the number of intervals.

3. Plant trees on the square line, if you want to plant trees at every vertex. then the number of trees = (the number of trees on each side 1) the number of sides.

1 The problem of tree planting on non-closed routes can be divided into the following three situations:

If trees are to be planted at both ends of the unenclosed line, then:

Number of plants = number of sections + 1 = full length plant spacing + 1

Full length = plant spacing (number of plants 1).

Plant spacing = total length (number of plants 1).

If trees are to be planted at one end of the unenclosed line and not at the other end, then:

Number of plants = number of segments = full length plant spacing.

Overall length = plant spacing Number of plants.

Plant spacing = total length number of plants.

The formula for the question of profit and loss.

Profit + loss) The difference between the two distributions = the number of shares participating in the distribution.

Big Profit Small Profit) The difference between the two distributions = the number of shares participating in the distribution.

Big loss, small loss) The difference between the two distributions = the number of shares participating in the distribution.

The formula for the encounter problem.

Encounter distance = speed and meeting time.

Encounter time = encounter distance speed and.

Speed and = Distance of Encounter, Time of Encounter.

Tree planting problem formula.

Unilateral tree planting (planting at both ends): distance number of intervals +1 = number of starvations.

Unilateral tree planting (planting only one end): distance Number of intervals = number of trees.

Unilateral tree planting (no planting at both ends): distance Number of intervals 1 = number of trees.

Bilateral tree planting (planting at both ends) Yuanzheng: (distance interval number + 1) 2 = number of trees.

Bilateral tree planting (only one end is planted) :(distance number of intervals) 2 = number of trees.

Bilateral tree planting (no planting at both ends) :( distance Number of intervals - 1) 2 = number of trees.

Cyclic tree planting: distance Number of intervals = number of trees.

Explanation: 1 The problem of tree planting on non-closed routes can be divided into the following three situations:

If trees are to be planted at both ends of the unenclosed line, then:

Number of plants = number of sections + 1 = full length plant spacing + 1

Full length = plant spacing (number of plants 1).

Plant spacing = total length (number of plants 1).

If trees are to be planted at one end of the unenclosed line and not at the other end, then:

Number of plants = number of segments = full length plant spacing.

Overall length = plant spacing Number of plants.

Plant spacing = total length number of plants.

If trees are not planted at both ends of the unenclosed line, then:

Number of plants = number of sections + 1 = full length plant spacing + 1

Full length = plant spacing (number of plants 1).

Plant spacing = total length (number of plants 1).

2 The relationship between the number of tree planting problems on closed lines is as follows.

The number of plants = the number of sources of the rotten cavity = the total length of the plant spacing.

Overall length = plant spacing Number of plants.

Plant spacing = total length number of plants.

3 divided by 3 = 1 minute 1 divided by 2 = minutes multiplied by 5 = minutes.

It's 5 meters. Because of the 46 street lamps Kaisong, the interval is 45, so the bridge length is 45 3 = 135 meters, and the difference is only 28 street lights, and the interval is 27 staring at Qingzheng, so the interval is 135 27 = 5 meters.

The 46 Qingweizi street lamps have 45 spacing.

Bridge length: 45*3=135 meters.

There are 28 street lights, so there are 27 spacing.

Interval: 135 27 = 5 meters.

1. Plant at both ends: number of intervals + 1 = number of trees Number of intervals = number of trees - 1

2. Do not plant at both ends: the number of intervals - 1 = the number of trees The number of intervals = the number of trees + 1

3. One end planting (closed graphic): the number of intervals = the number of trees.

Determine the number of intervals first, and then consider the relationship between the tree and the number of intervals according to the topic.

The distance between the Elephant House and the Monkey Mountain is 60 meters (no planting at both ends), and the distance between the two adjacent trees is 3 meters.

Not closed case.

1. Ask for a tree.

The number of intervals is equal to the distance divided by the spacing.

Plant both: A tree is equal to the number of intervals plus one.

One plant: One tree is equal to the number of intervals.

Neither end is planted: a tree is equal to the number of intervals minus one.

2. Seek the distance.

The number of intervals multiplied by the spacing equals the distance

Plant both ends: the number of intervals is equal to one tree minus one.

One plant: The number of intervals is equal to one tree.

Neither end is planted: the number of intervals is equal to one tree plus one.

Closed case:

As in the case of a head-to-head plant, opening the closed shape is a head-end plant.

1 The problem of tree planting on non-closed routes can be divided into the following three situations:

If trees are to be planted at both ends of the unenclosed line, then:

Number of plants = number of sections + 1 = full length plant spacing + 1

Full length = plant spacing (number of plants 1).

Plant spacing = total length (number of plants 1).

If trees are to be planted at one end of the unenclosed line and not at the other end, then:

Number of plants = number of segments = full length plant spacing.

Overall length = plant spacing Number of plants.

Plant spacing = total length number of plants.

If trees are not planted at both ends of the unenclosed line, then:

Number of plants = number of sections + 1 = full length plant spacing + 1

Full length = plant spacing (number of plants 1).

Plant spacing = total length (number of plants 1).

2 The relationship between the number of tree planting problems on closed lines is as follows.

Number of plants = number of segments = full length plant spacing.

Overall length = plant spacing Number of plants.

Plant spacing = total length number of plants.

Tree planting problem formula.

Straight Tree Planting: Distance Interval +1 = Number of Trees.

Trees planted around: Distance Interval = Number of trees.

Tree planting between buildings: Unilateral tree planting Distance Interval -1 = tree.

Bilateral tree planting ( distance interval -1) 2=trees.

What is the formula for calculating the problem of tree planting?

Plant only one end): distance interval length = number of trees.

Not planted at both ends): distance interval length 1 = number of trees.

The total length of the route is divided into several sections by the trees, and the relationship between the number of sections and the number of trees planted varies depending on the route and the requirements for tree planting.

Now that we understand what a tree planting problem is, when solving a tree planting problem, we first understand the amount of several solutions: interval (the part between two trees), interval length (the length between two trees), number of intervals (number of intervals), number of trees (number of trees), distance (total length of the line).

Extended Materials. 1. If trees are to be planted at both ends of the tree planting line, then the number of trees planted should be 1 more than the number of sections to be divided, that is: the number of trees = the number of intervals + 1.

2. If there is only one end of the tree planting line to be planted, then the number of trees to be planted and the number of sections to be divided are equal, that is: the number of trees = the number of intervals.

3. If no trees are planted at both ends of the tree planting line, then the number of trees planted is less than the number of sections to be divided by 1, that is: the number of trees = the number of intervals 1.

4. If trees are planted on both sides and at both ends of the tree planting route, then the number of trees planted should be 1 more than the number of sections to be divided, and then multiplied by two, that is: one tree = number of sections + 1 and then multiplied by two.
