我是新手,请帮忙看看代码,是不是因为循环太多超时的?谢谢!#include <stdio.h> #include <stdlib.h> #include <string.h> #include <math.h> int main() { int n,m,i,j,k,num; scanf("%d",&n); getchar(); int **count; char **str; count=(int **)malloc(2*n*sizeof(int *)); str=(char **)malloc(2*n*sizeof(char *)); for(i=0;i<2*n;i++) { count[i]=(int *)malloc(26*sizeof(int)); str[i]=(char *)malloc(50*sizeof(char)); memset(count[i],0,26*sizeof(int)); } for(i=0;i<2*n;i++) { j=0; scanf("%c",str[i]+j); while(str[i][j]!='\n') { count[i][str[i][j]-97]++; j++; scanf("%c",str[i]+j); } } for(i=0,k=1;i<2*n-1;i+=2) { num=0; for(j=0;j<26;j++) { m=count[i][j]-count[i+1][j]; if(m==0) continue; num+=abs(m); } printf("Case #%d: %d\n",k,num); k++; } for(i=0;i<2*n;i++) { free(count[i]); free(str[i]); } free(count); free(str); return 0; } Followed by:
