Coin ChangeYou is given coins of different denominations and a total amount of money amount. Write a function to compute the fewest number of coins so need to make up that amount. If that amount of cannot is made up by any combination of the coins, return -1 .Example 1:Coins = [1, 2, 5] , amount =11return 3 (11 = 5 + 5 + 1)Example 2:Coins = [2] , amount =3Return -1 .Note:You may assume so you have a infinite number of each kind of coin.Credits:Special

UVA_10328 This is very similar to the previous topic that calculates the probability that the number of consecutive victories is k, so I moved the idea used for that question. We set f [I] [j] to indicate the total number of consecutive H numbers not exceeding j when throwing the I-th coin. Since the I-th coin can be positive or negative, therefore, you may first write f [I] [j] = 2 * f [I-1] [j]. But in so

If there is a currency, it has 1 cents, 2 points, 5 points and 1 corners of the coin, at least how many coins to find the K-penny change?According to the idea of greedy algorithm, it is necessary to use the coin with the most face value constantly. If the value of change is less than the maximum coin value, try the second largest

Problem Description in a country with only 1 cents, 2 cents, 3 cents, there are many ways to exchange money n coins. Please write a procedure to figure out how many kinds of methods are in common. Input is only one positive integer per line n,n less than 32768. Output corresponds to each input, the number of conversion methods. Sample Input 2934 12553 Sample Output 718831 13137761 Author Smallbeer (CML) Train of thought: This question is the basis of the complete knapsack problem. Only 3 coins,

How to develop a virtual coin purseThe development of Bitcoin has been pursued by a large number of internet people and financiers, and there is no doubt that this is a social experiment on money, and that the number of participants is already around tens of millions of people worldwide. It's not hard to issue and develop a Bitcoin-like virtual currency, and our team now has a proven approach, from the development of wallets, to the development of min

HDU 2069 Coin Change functions HDU 2069 Coin Change functions This question is a little more complex than a common primary function to solve the problem. The number of components is limited and the number of combinations cannot exceed 100 coins. Therefore, c1 and c2 are defined as two-dimensional arrays, c1 [I] [j] indicates c1 [Result] [number of results], and then a loop of traversal numbers is added.

I learned this before when I thought about greedy algorithms. In fact, the application of greedy algorithms is a prerequisite. Under the current situation, for example, the values of common 1, 2, and 5, 10 are carefully designed. In fact, most of them should use dynamic planning. Of course, this article only uses search. For details, refer to the following connection. For example, values 1 2 and 2 1 are the same. In integer decomposition, the array is incremented. For example, 10 is used to brea

If the violent enumeration complexity immediately soared to O (2^ (n+1)).So the introduction of a new algorithm, binary lookup: The value to be enumerated, the
