Solution: Zigzag Conversion

Explore the zigzag conversion problem where you rearrange characters by simulating row-based traversal. Learn to track current rows and direction to form the pattern, handle edge cases, and optimize time and space complexity in Go.

Statement

Given a string s and an integer numRows, rearrange the characters of s by writing them in a zigzag pattern across numRows rows, then reading the result row by row from top to bottom.

For example, writing "COMPUTER" in a zigzag pattern across 3 row produces:

C U
O P T R
M E

This will be read as "CUOPTRME".
