/* 
* The string "PAYPALISHIRING" is written in a zigzag pattern on a given number of rows like this: (you may want to display this pattern in a fixed font for better legibility)
* 
* P   A   H   N
* A P L S I I G
* Y   I   R
* And then read line by line: "PAHNAPLSIIGYIR"
* 
* Write the code that will take a string and make this conversion given a number of rows:
* 
* string convert(string s, int numRows);
* Example 1:
* 
* Input: s = "PAYPALISHIRING", numRows = 3
* Output: "PAHNAPLSIIGYIR"
