D. Powerful array time limit per test seconds memory limit per test megabytes input standard input output standard output An array of positive integers a1, a2, ..., an ..., ar, ≤ l ≤ r ≤ n. For every positive integer s denote by Ks the number of occ
比如a[]={2,4,5,6,7},得出的两组数{2,4,6}和{5,7},abs(sum(a1)-sum(a2))=0: 比如{2,5,6,10},abs(sum(2,10)-sum(5,6))=1,所以得出的两组数分别为{2,10}和{5,6}. vector<int> vct; int last = INT_MAX; int halfOfSum(int* arr, int len) { int sum = 0; for (int i = 0; i < len; ++i) { sum
python简单方法判断三个数能否组成三角形 #encoding=utf-8 import math while True: str=raw_input("please input three numbers a,b,c:('stop' to exit)") print "####",str,type(str) if str !="stop": x,y,z = eval(str) min_value=min(x,y,z) max_value=ma
题:输入三个数a,b,n,输出a和b不大于n的公倍数的所有个数. 这题的思想是先求得a和b的最大公约数,然后用a和b的积除以最大公约数,得到最小公倍数,再持续加上最小公倍数,直到超过n,记下n的个数.如:8,12,100,最大公约数为4,则最小公倍数为24.则公倍数为:24.48.72.96,即总共有4个. 代码如下: #include<iostream> #include<algorithm> using namespace std; int main() { int a, b,
