Calculate a+b and output the sum in standard format -- that is, the digits must be separated into groups of three by commas (unless there are less than four digits).
Each input file contains one test case. Each case contains a pair of integers a and b where −106≤a,b≤106. The numbers are separated by a space.
For each test case, you should output the sum of a and b in one line. The sum must be written in the standard format.

コード:#include#include using namespace std;int main() { int a,b; int sum; stackst; while(~scanf("%d%d",&a,&b)) { sum = a+b; if(sum==0) { printf("0"); continue; } else if(sum<0) printf("-"); sum = abs(sum); int s = 0; while(1) { st.push(sum%10+'0'); sum = sum/10; if(sum==0) break; s++; if(s%3==0) st.push(','); } while(!st.empty()) { printf("%c",st.top()); st.pop(); } printf(""); } return 0; }
Input Specification:
