One Away Transformation Problem

Given two strings, A and B, determine whether A can be transformed into B by performing at most one of the following operations (including zero operations):

1. Delete a character from any position. 2. Replace a character with any other character. 3. Insert a character at any position.

Input:

Input begins with a single integer T, which stands for the number of test cases. Each test case has two lines: the first line is a string A, and the second line is a string B.

Output:

For each test case, output "True" if string A can be transformed into string B, "False" otherwise.

Example:

Input: T = 1 A = "pale" B = "ple" Output: True

Constraints:

1 ≤ T ≤ 100

1 ≤ |A| ≤ 10⁴

1 ≤ |B| ≤ 10⁴

Both strings contain only lowercase English letters.

Note:

You do not need to print anything; it has already been handled. Just implement the function provided.

Accepted Answer

Determine if one string can be transformed into another by performing at most one operation (insert, delete, replace).

Iterate through both strings simultaneously and check for differences.
Handle cases where a character needs to be inserted, deleted, or replaced.
Keep track of the number of operations performed and ensure it does not exceed one.
