Give the following four questions 20

One (3rd).

The first one needs to use a conditional statement to determine whether x is greater than 0;

The second one needs to use a conditional statement to determine whether x is greater than or equal to 0;

The fourth is to use conditional statements to determine whether A is less than B and whether A is less than C (or change the order).

The first one uses sqrt().

the second if(x>=0) f=x*x+1;

else f=x-1;

The third is direct 6*6

The fourth sort with sort comes to mind.

, b is x 2 + x - 1 = 0 two feet to know the void root.

Veda's theorem: Sharp grip ab=-1 a+b=-1 --ab+a+b=-2a=cos60+isin60 or cos-60+isin-60-> silver trap qing a 2007=a 3 a 454=a 4->a 4+a 3+a 2=-2

a=cos120+isin120 or cos240+isin240

a 2001 = 1 a 322 = a a 2 = a 2 original = 1 + a + a 2 = 0

a=(1±√5)/2

a^18+a^(-6)*323=5796

Question 1: He's a poor bastard, why, because if he's really so rich, the women will stick to him upside down, and he will go to the dating network, and there are so many books in the main book, which is easy to deceive people and tell a lie to round a lie.

Question 2: What kind of rich people look like silver, some are working in the company, some are doing things outside, and there may be some impossible, this question is meaningless.

3 The credibility scum is almost zero, and I guess there is still a wife.

4 What kind of person is he then I have to ask you, some murderers and some people think he is good, and some are philanthropists and say that others are bad, this may not be, but from this it seems that it is not as good as the yard is very good, and it is estimated that there are two cheats with you, or cheat money.

Question 5 is purely a personal opinion, if there are similarities.

1) The 2 yuan was added repeatedly, it should be 9*3-2+5 302) There is a problem with the price of the person who sells green onions. He thought that the green onion was 7 cents a pound of white and 3 cents of green onions, which together were a piece. Actually, it's wrong.

One pound and one pound of green, a total of 2 pounds. It should be 2 yuan to not lose money.

3) A total of five days.

On the first day, climb 3 meters, retreat 2 meters, actually climb 1 meter, and leave 6 meters.

Climb 3 meters on the second day, retreat 2 meters, actually climb 1 meter, plus 2 meters on the first day, then there are 5 meters left.

On the third day, climb 3 meters, dig and retreat 2 meters, actually climb 1 meter, and the second day is 3 meters, then the remaining height is 4 meters.

On the fourth day, climb 3 meters, retreat 2 meters, actually climb 1 meter, plus the third day is 4 meters, then there are 3 meters left.

On the fifth day, I climbed 3 meters and came out.

4) Buy 9 first, then have three peach pits, exchange for a peach, buy back a peach for the remaining dime, eat two peach pits, and then "borrow" a peach pit, exchange for a peach, and eat the remaining peach pits Qi San to return the borrowed just now. 9 + 3 + 1 + 1 + 1 = 15.

1.Why do rich people have money, it is because they pick out the door, so they generally don't show off their wealth, because they are quite stingy.

2.Playing QQ often has nothing to do with being rich or not, it's a hobby problem, but, if you are rich, then business must be very busy, and there shouldn't be so much leisure time to be decadent.

3.There are many contradictions in what he does and what he says, and there is no credibility to speak of.

4.No matter how stupid anyone is, they can see that he is definitely a **!!

A word of advice, don't have any involvement and connection with this kind of person, even if you are smart, you will be fooled if you have been deceived for a long time.

Are rich people afraid that they won't find a partner? People who can make money will be q every day? Don't delay making money?

Personally, I feel that he is a guy who has no money and then cheats people's feelings on ......Quickly cut off contact.

The network is inherently virtual, and who knows if the person on the other side of the conversation with you is a woman. I'm the same as you, that person also told me that he was out of town, let me accompany him to stay abroad for a year, and when he came back, he gave me a TT, and also told me that he used a lot, but it was inconvenient to tell me. I accidentally sent him my number, and he messaged me back, and it turned out to be tragic.

It's a homosexual! I wanted to die at that time. Don't care too much about the virtual world, how can rich people have so much time to QQ, people generally MSN, email, Weibo.

A man who loves you will take you to meet his friends and family, it is obvious that he is lying to you, I don't know what you are still hesitating about, what else can you believe, is you still a little nostalgic because of money, it's really not worth it.

What is your purpose in looking for him? Friend?? Affection?

Money? Or is it something else? If you are a friend, you don't need to care about his social status!

If you don't have those purposes, you don't need to pay attention to who he is! By the way, if you really approach him with a purpose, you must be the one who gets hurt in the end!

Regardless of other factors, I can be sure that this person is not a successful person. And moral decay. If you don't look back, just wait to be deceived.

1，**。

2，**。3. Don't believe it.

4, it's strange to believe in him.

1.He wants to get some benefits by making friends, or he is really free, depending on his registration level.

2.Not necessarily, rich people generally play bigger entertainment, but it can't be denied that it is possible, it depends on his QQ level and recharge items.

4.Maybe it's a ** who collects benefits from it, or maybe it's a very idle person.

**Or fugitives, report live away, you are not deep!

How much do you think his words are credible?
