1.Title : 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 RAnd 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"
.2.pseudocode :
1 creat data structure: 2 the given number of rows → nRows; 3 the given text string → s; 4 stringBuffer[] to restore result → sb; 5 set char position index i = 0;row position index j = 0;combing outcome index k = 1; 6 while i < the length of s,then 7 for each j from 0 to (nRows - 1) 8 append the ith char of s to sb[j]; 9 i++; 10 end 11 for each j from (nRows - 2) to 1 12 append the ith char of s to sb[j]; 13 i++; 14 end 15 end 16 //form a united outcome 17 for each k from 1 to (nRows - 1) 18 append sb[k] to sb[0]; 19 end 20 terminate and output sb[0];
