Leetcode 6 ZigZag Conversion Simulation Difficulty: 0

https://leetcode.com/problems/zigzag-conversion/

The string is "PAYPALISHIRING" written with 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   NA p L S i i GY   i   R

And then read on line:"PAHNAPLSIIGYIR"

Write the code that would take a string and make this conversion given a number of rows:

String convert (string text, int nRows);

convert("PAYPALISHIRING", 3)should return "PAHNAPLSIIGYIR" .

Class Solution {public:    string Convert (string s, int numrows) {        if (numrows = = 1) return s;        string* a = new string[numrows];        string ans;        int n = 2 * numRows-2;        for (int i = 0;i < S.size (); i++)        {            int r = i% n;            int L = r% NumRows;            if (L = = r) a[l] + = s[i];            Else A[numrows-l-2] + = S[i];        }        for (int i = 0;i < numrows;i++) {            ans + = a[i];        }        return ans;    };
