My issue

i got output wrong i want correct code for this

My code

import sys
import math

def min_boxes_with_m_balls(test_cases):
    results = []
    
    for N, M, A in test_cases:
        total_boxes_with_m_balls = 0
        
        for a in A:
            total_boxes_with_m_balls += (a + N - 1) // N  
        
        results.append(total_boxes_with_m_balls)
    
    return results

input_data = sys.stdin.read().strip().splitlines()
T = int(input_data[0])  # number of test cases
index = 1
test_cases = []

for _ in range(T):
    N, M = map(int, input_data[index].split())
    index += 1
    A = list(map(int, input_data[index].split()))
    index += 1
    test_cases.append((N, M, A))

results = min_boxes_with_m_balls(test_cases)

for result in results:
    print(result)
