  Medium
  
  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"
  Example 2:
  
  Input: s = "PAYPALISHIRING", numRows = 4
  Output: "PINALSIGYAHRPI"
  Explanation:
  
  P     I    N
  A   L S  I G
  Y A   H R
  P     I
