题意: 给出一个整数N,输出N^N(N的N次方)的十进制表示的末位数字. Input 一个数N(1 <= N <= 10^9) OutPut 输出N^N的末位数字 思路: EASY,,,,,, 代码: int calc(int t,int n){ if(n==0) ret 1; if(n==1) ret t; int s=calc(t,n/2); s=s*s%10; if(n&1){ s=s*t%10; } ret s; } int main(){ int n; cin>>…
Given a non-negative integer num represented as a string, remove k digits from the number so that the new number is the smallest possible. Note: The length of num is less than 10002 and will be ≥ k. The given num does not contain any leading zero. Ex…
