哪位大牛给看看?我实在是找不出错在哪里。本代码已通过题目中的范例输入数据。#include<stdio.h> #include<string.h> #include <iostream> #include <algorithm> using namespace std; void init(int letter[52]) { for(int i=0;i<52;i++) letter[i]=0; } void statistic(int letter[52],char input[13]) { for(int i=0;i<strlen(input);i++)//去除最后一个回车 { if(input[i]<='Z') letter[(input[i]-'A')*2]++; else letter[(input[i]-'a')*2+1]++; } } void sort(char input[]) { int j=0; int letter[52]; init(letter); statistic(letter,input); for(int i=0;i<52;i++) { while(true) { if(letter[i]!=0&&i%2==0) { input[j++]=i/2+'A'; letter[i]--; } else if(letter[i]!=0&&i%2==1) { input[j++]=i/2+'a'; letter[i]--; } else break; } } } main() { char input[13]; char y[13]; int i,j; int test; scanf("%d",&test); getchar(); for(i=0;i<test;i++) { gets(input); sort(input); puts(input); strcpy(y,input); while(next_permutation(input,input+strlen(input))) { if(strcmp(input,y)!=0) puts(input); strcpy(y,input); } } } Followed by: Post your reply here: |
