In the last season of Attack on Titan, there were N episodes numbered from 1 to N.
Each even indexed episode was A minutes long and each odd indexed episode was B minutes long.

Calculate the total duration (in minutes) of the last season.

Input Format

  • The first line of input contains a single integer T, the number of test cases.
  • The first and only line of each test case contains three integers N, A, and B, the number of episodes and the durations of each even-indexed and odd-indexed episodes respectively in minutes.

Output Format

For each test case, print a single integer on a new line, the total duration of the last season in minutes.

Constraints

  • 1≤T≤100
  • 1≤N≤60
  • 1≤A,B≤60

Sample 1:

Input 
3
1 2 2
2 3 4
4 20 30

Output
 
2
7
100

Solution
T = int(input())  

for _ in range(T):
    N, A, B = map(int, input().split())
    odd_count = (N + 1) // 2
    even_count = N // 2
    total_duration = odd_count * B + even_count * A
    print(total_duration)
