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".
class Solution { public: string convert(string s, int nRows) { string s0; vector<string> vs(nRows,s0); int len = s.size(); for(int i=0;i<len;){ for(int j=0;j<nRows && i<len;j++){ vs[j].push_back(s[i]); i++; } for(int k=nRows-2;k>0 && i<len;k--){ vs[k].push_back(s[i]); i++; } } string result; for(int i=0;i<nRows;i++){ result += vs[i]; } return result; }//end func };
