Solution: Zigzag Conversion

Explore how to solve the Zigzag Conversion problem by tracking characters across rows in a zigzag pattern. Learn to implement this solution efficiently in JavaScript, understand edge cases, and analyze its time and space complexity.

We'll cover the following...

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".
