Problem 1: Alternate Characters
Problem: Given a non-empty string, return a new string made of every second character starting with the first character (index 0). Examples: alternateChars("hello") → "hlo" alternateChars("abcdef") → "ace" alternateChars("12345") → "135" Solution Approach: Use a for loop with a step of 2 to select every other character.
