各位高手帮忙看看;为啥是WA?#include <stdio.h> void main(){ char a[100][7],b; int n,i,j,x,s=0,p=1,d[100],r=0,k,q; long int w[100][2]; scanf("%d",&n); for(i=0;i<n;i++){ for(j=0;j<7;j++){ scanf("%c",&b); if(b>=48&&b<=57) a[i][j]=b; else if(b>=65&&b<=67) a[i][j]='2'; else if(b>=68&&b<=70) a[i][j]='3'; else if(b>=71&&b<=73) a[i][j]='4'; else if(b>=74&&b<=76) a[i][j]='5'; else if(b>=77&&b<=79) a[i][j]='6'; else if(b>=80&&b<=83) a[i][j]='7'; else if(b>=84&&b<=86) a[i][j]='8'; else if(b>=87&&b<=99) a[i][j]='9'; else j=j-1; } } for(i=0;i<n;i++) d[i]=1; for(i=0;i<n;i++){ if(a[i][0]=='e') continue; else { for(j=i+1;j<n;j++){s=0; for(x=0;x<7;x++){ if(a[i][x]==a[j][x]) s=s+1; } if(s==7) { a[j][0]='e'; d[i]=d[i]+1; d[j]=0; } } } } for(i=0;i<n;i++){ w[i][0]=0; if(a[i][0]!=101&&d[i]>1){ r=1; for(j=0;j<7;j++) w[i][0]=(a[i][j]-48)+w[i][0]*10; } } for(q=0;q<n;q++){k=0;for(j=0;j<n;j++){if(w[k][0]==0)k++; else break;} for(i=0;i<n;i++){ if(w[i][0]!=0&&w[k][0]>w[i][0])k=i; } if(a[k][0]!=101&&d[k]>1){ for(j=0;j<3;j++) printf("%c",a[k][j]); printf("-"); for(j=3;j<7;j++) printf("%c",a[k][j]); printf(" %d\n",d[k]); }w[k][0]=0; } if(r==0) printf("No duplicates. \n"); } Followed by:
