Different ways to create a 5x5 matrix initialized with zeros.

This file demonstrates three approaches for educational purposes.

# 1️⃣ Using nested loops
matrix_loop = []
for row in range(5):
    matrix_loop.append([])

# 2️⃣ Using list comprehension (recommended)

# 3️⃣ Using multiplication (be careful with nested lists!)
matrix_multiplication = [[0] * 5 for _ in range(5)]
