/************************************************************************
*
* 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 text, int nRows);
*
* convert(“PAYPALISHIRING”, 3) should return “PAHNAPLSIIGYIR”.
*
