coin vector

In my opinion, this thing about vectors should be an enhanced version of the array.Need header file when using #include Advantages of the vector container: ① is not prone to overflow, it automatically adjusts the data size to accommodate the element you put in ② is that it has many ways to manipulate the elementsDeclaration Initialization:Vector Cases:Vector //Declare an int type vector aVector //declarati

There are five types of coins: 1, 5, 10, 25, 50. Now let's get a number of n. What is the total number of solutions to combine these five coins and n? Solution: Dynamic Planning1: If a coin consists of only one cent, the total number of coins is 1.2: If a coin is composed of 1 and 5, the total number of solutions is 1 + s1 (s1 is a solution consisting of 1 and 5)...6: If a

Say this is our school summer camp finished a problem, just see thought is to water problem, later found the complexity is too big, can not stand, the game finished also did not get out, then said this is binary enumeration. Then the touch of the study, and then wrote the word, The so-called binary enumeration is to calculate the first half, then half, and then use the two-point search to see if we can get this state, if it is possible, Test instructions: Give you two number n,k, the followi

Title: Give the value of 4 coins and the number of limits, how many ways to make up s block money.Idea: A very ingenious idea that used 4 of this very small number. We can go ahead and run a full backpack, regardless of the number of each coin. Then you can remove the non-conforming situation. The method is to subtract the number of the extra limit of a coin, then add the number of the two kinds of coins ov

Q1: Now there are 9 coins, one is lighter than the other 8, give a no weight balance, at least a few times can be weighed light coins??A1: The dichotomy can be used, but here is the three-point method is better. Q2: Following Q1, if there are 10 coins? 12 of them? 100 of them? What about n?A2: first three points, in the narrow three-point range. Q3:9 a coin, there is one and the other 8 different weight, but do not know is more than the other 8 light
