Pattern Bus

Problem Statement

You are playing the famous BUS game with your friend, where you need to say “BUS” for multiples of 5 instead of saying the number itself. So, the sequence goes:

(1), (2), (3), (4), (BUS) (6), (7), (8), (9), (BUS), …, (N-1), (N)

You need to print this sequence in a slightly different matrix format, whose dimensions are N and M.

Input Format:

• The first line contains one integer, T, the number of test cases.
• Each test case contains two integers N and M on a separate line, denoting the number of rows and columns respectively.

Output Format:

Print the BUS sequence in matrix form with N x M elements.

Constraints:

• 1 ≤ T ≤ 10
• 10 ≤ N, M ≤ 10₃

Solution

for _ in range(int(input())):
    n, m = map(int, input().split())
    cnt = 1
    for i in range(n):
        res = []
        for j in range(m):
            res.append('(BUS)' if cnt % 5 == 0 else res.append(f'({cnt})'))
            cnt += 1
        print(' '.join(res))
