#dynamic-programming In Byteland they have a very strange monetary system. Each Bytelandian gold coin has an integer number written on it. A coin n can be exchanged in a bank into three coins: n/2, n/3 and n/4. But these numbers are all rounded down (the banks have to make a ...
n =5, returntrue. Challenge O(n) time and O(1) memory 这个题目是属于经典的博弈类Dynamic Programming 的入门题目, 为了便于思考, 我们只考虑一个选手的status, 例如我们只考虑first player的状态, 然后 A[i] 表明到first player下时还 剩下i个coins, 找到动态关系式: A[i] = (A[i-2] and A[i...
#dynamic-programming#datastructures Ada the Ladybug has several coins in her wallet. She is wondering, how many different values [sum of some subset of coins] is she able to make (in given range). Input The first line contains two integer numbers1 ≤ N ≤ 104, 1 ≤ Q ≤ 5*105, the...

COINS - Bytelandian gold coins #dynamic-programming In Byteland they have a very strange monetary system. Each Bytelandian gold coin has an integer number written on it. A coin n can be exchanged in a bank into three coins: n/2, n/3 and n/4. But these numbers are all rounded down...
The 1D version of this problem: maximize the sum of non-adjacent numbers (when we pick i-th number, two numbers next to it (i-1, i+1) disappear). We can solve this via Dynamic Programming Algorithm: Base conditions: and represents the maximum sum we can get for numbe...
The problem is that the most volatile cryptocurrencies won’t show up on the sites mentioned above, soDEX Screeneris your friend here. You can find pretty much any cryptocurrency on here, even if it was created this afternoon. Short-term vs. Long-term Analysis: If you’re looking for crypt...
1 <= piles[i] <= 500 sum(piles)is odd. 这个题目思路跟[LintCode] 395. Coins in a Line 2_Medium tag: Dynamic Programming, 博弈很像, 只不过这里是利用 区间Dynamic Programing的方法,所以只用一维的dp已经不够了, 另外初始化的时候我们不直接用for loop, 而是用类似于dfs recursive的方法去将初始化...
