+	Explanation:
+	The code snippet is implementing the "One Edit Away" algorithm, which determines whether two given 
+	strings are one edit away from each other. An edit is defined as either inserting a character, removing a character, or replacing a character.
+
+	The `OneEdit` function takes two strings as input and returns a boolean indicating whether 
+	they are one edit away. Here's the breakdown of the algorithm:
+
+	1. Calculate the lengths of the two strings.
+	2. Check if the difference in lengths is greater than 1. If so, return `false` because it's 
+	   not possible to make one edit to make the strings equal.
+	3. Traverse both strings until the shorter one is fully traversed or an unequal character is 
+	found.
+	4. If an unequal character is found, check the remaining portion of the strings to determine 
+	   if they are still one edit away.
+	5. Check the remaining characters in the longer string compared to the remaining characters 
+	   in the shorter string.
+	6. Return `true` if the remaining portions match, indicating they are one edit away.
+	7. If the loop completes without finding any unequal characters, the strings are either 
+	   identical or differ only in length by 1, which means they are one edit away.
+	8. The `abs` and `min` functions are utility functions used to calculate the absolute value 
+	   and minimum of two integers, respectively.
+
+	The algorithm efficiently checks for the possibility of one edit by comparing the characters at corresponding indices and handling cases where the lengths of the strings are different.
