哪位高手帮忙看下,数据都通过了,就是WA#include <iostream> #include <cstring> using namespace std; void swap1(char a[]); int main() { int N; char sums[82]; while(scanf ("%d",&N)!=EOF) { for(int ii=1;ii<=N;ii++) { char first[81],second[81]; char len; char sum[82]; memset(sum, 0, sizeof(sum)); sum[0]='0'; scanf("%s %s",&first,&second); if(strlen(first)>strlen(second)) len=strlen(first); else len=strlen(second); swap1(first); swap1(second); for(char i=0;i<len;i++) { if(first[i]!='0'&&first[i]!='1') first[i]='0'; if(second[i]!='0'&&second[i]!='1') second[i]='0'; if(sum[i]!='1') sum[i]='0'; sum[i]+=first[i]+second[i]-'0'-'0'; if(sum[i]>='2') { sum[i]-=2; sum[i+1]='1'; } if(i==len-1) if(sum[i+1]=='1') sum[i+2]='\0'; else sum[i+1]='\0'; } swap1(sum); int k=0,l=strlen(sum); for(int j=0;j<strlen(sum);j++) { if(sum[j]=='1'){l=j;break;} } for(int dd=l;dd<strlen(sum);dd++) { sums[k]=sum[dd]; k++; } sums[k]='\0'; if(sums[0]=='\0') printf("%d 0\n",ii); else printf("%d %s\n",ii,sums); } } return 0; } void swap1(char a[]) { char len,temp; len=strlen(a); for(char i=0;i<len;i++) { if(i==len-i-1||i==len-i) break; temp=a[i]; a[i]=a[len-i-1]; a[len-i-1]=temp; } } Followed by: Post your reply here: |
