How to simplify the solution to traverse the list fewer times?

To go through the list fewer times and simplify the solution, it is worth combining all necessary operations into one pass. For example, if you need to find the maximum, minimum, and sum of elements simultaneously, you can do this in one loop instead of three separate ones.

Example in Python:

numbers = [3, 7, 2, 9, 4]
max_val = numbers[0]
min_val = numbers[0]
sum_val = 0

for num in numbers:
    if num > max_val:
        max_val = num
    if num < min_val:
        min_val = num
    sum_val += num

print(f"Maximum: {max_val}, Minimum: {min_val}, Sum: {sum_val}")

This approach reduces the number of data passes, which improves performance, especially on large datasets.
