1065 A+B and C (64bit) (PTA)

Given three integers AB and C in [−2​63​​,2​63​​], 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 AB 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

N = int(input())

index = 1
while(index<=N):
    flag = 0
    a, b, c = map(int,input().split(' '))
    if a>0 & b>0 & a+b<0:
        flag = 1
    elif a<0 & b<0 & a+b>=0:
        flag = 0
    elif a+b>c:
        flag = 1
    print('Case #{}:'.format(index),"true" if flag else "false")
    index +=1
