为什么我一直RE啊#include<stdio.h> #include<string.h> char str1[1000],str2[1000],str[1000],mid[1000]; int main() { int i,j,k,t,len1,len2,len,max; char carry[2]; scanf("%d\n",&t); k=0; while(t--) { k++; //scanf("%s",str1); //scanf("%s",str2); gets(str); i=0; while(str[i]!=' ') { str1[i] = str[i]; i++; } str1[i]='\0'; strcpy(str2,&str[i+1]); len1 = strlen(str1); len2 = strlen(str2); // printf("%d %d\n",len1,len2); carry[0]='0'; carry[1]='\0'; if(len1>len2) { strcat(carry,str1); strcpy(str1,carry); for(i=0;i<=len1-len2;i++) mid[i]='0'; mid[i]='\0'; strcat(mid,str2); strcpy(str2,mid); } else if(len2>len1) { strcat(carry,str2); strcpy(str2,carry); for(i=0;i<=len2-len1;i++) mid[i]='0'; mid[i]='\0'; strcat(mid,str1); strcpy(str1,mid); } else { strcat(carry,str1); strcpy(str1,carry); carry[0]='0'; carry[1]='\0'; strcat(carry,str2); strcpy(str2,carry); } //printf("%s %s\n",str1,str2); // printf("%s %s\n",str1,str2); carry[0]='0'; max = (len1>len2)?len1:len2; for(i=max;i>=0;i--) { if(str1[i]=='0'&&str2[i]=='0') { if(carry[0]=='0') str[i]='0'; else if(carry[0]=='1') {str[i]='1'; carry[0]='0';} } else if(str1[i]=='0'&&str2[i]=='1') { if(carry[0]=='0') str[i]='1'; else if(carry[0]=='1') { str[i]='0'; carry[0]='1';} } else if(str1[i]=='1'&&str2[i]=='0') { if(carry[0]=='0') str[i]='1'; else if(carry[0]=='1') { str[i]='0'; carry[0]='1';} } else if(str1[i]=='1'&&str2[i]=='1') { if(carry[0]=='0') { str[i]='0'; carry[0]='1';} else if(carry[0]=='1') { str[i]='1'; carry[0]='1';} } } str[max+1]='\0'; i=0; while(str[i]=='0') i++; if(str[i]=='\0') i = i-1; printf("%d %s\n",k,&str[i]); } return 0; } Followed by: Post your reply here: |
