Problem

Given a list of integers, write a function that returns the largest difference between any two adjacent elements in the list.
Example input: [2, 4, 1, 16, 7, 5]
Example output: 15

Solution

def largest_difference(list):
    
    This function takes a list of integers and returns the largest difference between any two adjacent elements in the list.
    
    # Initialize the largest difference to 0
    largest_diff = 0
    # Loop through the list
    for i in range(len(list) - 1):
        # Calculate the difference between the current element and the next element
        diff = list[i] - list[i + 1]
        # If the difference is negative, make it positive
        if diff < 0:
            diff = diff * -1
        # If the difference is larger than the largest difference, update the largest difference
        if diff > largest_diff:
            largest_diff = diff
    # Return the largest difference
    return largest_diff

# Test the function
print(largest_difference([2, 4, 1, 16, 7, 5]))



This solution is optimal because it only loops through the list once.
