**Finding the Largest Number in a List**

To create an algorithm that identifies the largest number within a list, it must be easily interpretable by those without programming knowledge. The steps should avoid using predefined functions or sorting methods, aiming for a straightforward conversion into a computer program if desired.

**Binary Search Algorithm Example:**

1. **Identify Midpoint**: Determine the center of the sorted array or list by halving its length.
   
2. **Comparison**: Assess whether the midpoint is greater or smaller than the target value.
   
3. **Adjust Search Range**:
   - If the midpoint exceeds the target, focus the search on the right half.
   - If the midpoint is less than the target, concentrate on the left half.
   
4. **Repeat**: Continue this approach until the midpoint matches the target value or confirms its absence in the list.

**How to Write an Algorithm to Calculate the Average of a List of Numbers**

When designing an algorithm to calculate the average of a list, it's important to make it understandable for those who may not be familiar with programming languages. The instructions should avoid using pre-defined functions but still be close to what a line-by-line program would entail.

**Example Algorithm for a Binary Search:**

1. Find the midpoint of the sorted array or list by dividing its length by 2.
2. Compare the midpoint to the value of interest.
3. If the midpoint is larger than the value, perform a binary search on the right half of the array.
4. If the midpoint is smaller than the value, perform a binary search on the left half of the array.
5. Repeat these steps until the midpoint value equals the value of interest or it is confirmed that the value is not in the array.

This approach allows the problem to be broken down into manageable steps, making complex tasks accessible even to those without coding knowledge.
