Question

How do you find the lowest and highest values in a list?

Short answer

Answer: To find the lowest and highest values in a given list, follow these steps: 1. Understand the problem: Compare each element in the list with the current highest and lowest values, updating them accordingly. 2. Define the initial lowest and highest values: Set the initial lowest and highest values to the first element in the list. 3. Iterate through the list: Use a loop to iterate through each element, starting from the second element. 4. Compare each element: Update the lowest and highest values based on the comparisons made during_each iteration. 5. Return the lowest and highest values: Once the entire list has been iterated through, return the final lowest and highest values.

Step-by-step solution

Understanding the problem

To find the highest and lowest values in a list, we need to compare each element in the list with the current highest and lowest values, and update them accordingly as we go through the list.

Define the initial lowest and highest values

At the beginning of the process, we need to set the initial lowest and highest values to the first element in the list. This provides a starting point for comparison.

Iterate through the list

Using a loop, we'll iterate through each element in the list, starting from the second element (since the first element is already set as the initial lowest and highest values).

Compare each element with the current lowest and highest values

As we iterate through the list, for each element, we'll compare its value with the current highest and lowest values. If the current element is lower than the current lowest value, we'll update the lowest value to the current element. Similarly, if the current element is higher than the current highest value, we'll update the highest value to the current element.

Return the lowest and highest values

Once we've iterated through the entire list and updated the highest and lowest value accordingly, we'll return those values as the final result.
