sort函数我是不是用错了?#include<stdio.h> #include<algorithm> bool cmp(int i,int j) { return i>j; } int power(int i,int e) { int r=1; for(int j=0;j<e;j++) r*=i; return r; } void main() { int n,e,r[105],t,total=0; scanf("%d",&n); scanf("%d",&e); for(int i=0;i<n;i++){ scanf("%d",&t); r[i]=power(t,e); } std::sort(r,r+n,cmp); i=0; while(r[i]>0) total+=r[i++]; printf("%d\n",total); } 为什么WA,不用sort就能AC Followed by:
