WA的同学注意了,字符串末位需加'\0',WA无数次的可以试试,觉得好用的请告诉我为什么#include <stdio.h> #include <string.h> #include <stdlib.h> int Comp(const void *p1,const void *p2) { return strcmp((char *)p1,(char *)p2); } int main() { char to[]={"22233344455566677778889999"}; // char alphaToNum[]={"ABCDEFGHIJKLMNOPQRSTUVWXYZ"}; int n,i,j,l,num,len; char p[101000][9]; char a[1000]; int flag; scanf("%d",&n); for(i=0;i<n;i++){ scanf("%s",a); j=0; for(l=0,len=strlen(a);l<len;l++){ if('A'<=a[l]&&a[l]<='Z') p[i][j++]=to[a[l]-'A']; else if('0'<=a[l]&&a[l]<='9') p[i][j++]=a[l]; if(j==3) p[i][j++]='-'; } p[i][8]='\0';////如果没有这句WA,添这句AC,注意注意!!!!!! } qsort(p,n,sizeof(p[0]),Comp); flag=1; for(i=0;i<n;i=j){ num=0; for(j=i;j<n&&!strcmp(p[i],p[j]);j++) num++; if(num>1){ printf("%s %d\n",p[i],num); flag=0; } } if(flag) printf("No duplicates.\n"); return 0; } Followed by: Post your reply here: |
