def merge_two_lists_into_one(num1, num2):
    numbers = [0] * (len(num1) + len(num2))
    i = 0
    j = 0
    k = 0

    while i < len(num1) and j < len(num2):
        if num1[i] <= num2[j]:
            numbers[k] = num1[i]
            i += 1
        else:
            numbers[k] = num2[j]
            j += 1
        k += 1

    while i < len(num1):
        numbers[k] = num1[i]
        i += 1
        k += 1

    while j < len(num2):
        numbers[k] = num2[j]
        j += 1
        k += 1
        
    return numbers;

num1 = [7, 3, 2, 9, 1]
num2 = [5, 8, 6, 4, 0, 11, 10, 12]

numbers = merge_two_lists_into_one(num1, num2)
