To implement a program that reverses the string “ABCDEFGHIJ”, we can employ the simplest method of swapping characters from the beginning and the end of the string until the middle is reached. The program will keep track of the number of exchange operations, comparison operations, and the number of loop executions.

Here is a breakdown of how the algorithm works:

### Algorithm:
1. Initialize pointers: Set two pointers, `left` and `right`, at the start and the end of the string, respectively.
2. Swap characters: Swap the characters at the `left` and `right` positions.
3. Increment pointers: Move the `left` pointer one position forward and the `right` pointer one position backward.
4. Repeat: Continue swapping until the `left` pointer is greater than or equal to the `right` pointer.

### Operations:
- Comparison operations: Each iteration of the loop checks whether `left < right`, ______ __________ _______ ___ ________.
