Given three integers A, B and C in [-263, 263], you are supposed to tell whether A+B > C.
Input Specification:
The first line of the input gives the positive number of test cases, T (<=10). Then T test cases follow, each consists of a single line containing three integers A, B and C, separated by single spaces.
Output Specification:
For each test case, output in one line "Case #X: true" if A+B>C, or "Case #X: false" otherwise, where X is the case number (starting from 1).
Sample Input:
3 1 2 3 2 3 4 9223372036854775807 -9223372036854775808 0
Sample Output:
Case #1: false Case #2: true Case #3: false
1 #include <stdio.h> 2 #include <stdlib.h> 3 #include <iostream> 4 #include <string.h> 5 #include <string> 6 #include <math.h> 7 #include <algorithm> 8 using namespace std; 9 10 11 int main(){ 12 13 int t,tcase=1; 14 scanf("%d",&t); 15 while(t--) 16 { 17 long long a,b,c; 18 scanf("%lld %lld %lld",&a,&b,&c); 19 long long res=a+b; 20 bool flag; 21 if(a>0&&b>0&&res<0)flag=true; 22 else if(a<0&&b<0&&res>=0)flag=false; 23 else if(res>c)flag=true; 24 else flag=false; 25 if(flag==true) 26 { 27 printf("Case #%d: true\n",tcase++); 28 }else 29 { 30 printf("Case #%d: false\n",tcase++); 31 } 32 } 33 return 0; 34 }
