Function zigzag_conversion

Source 
pub fn zigzag_conversion(
    s: String,
    n_rows: i32,
    alg: Option<Algorithm>,
) -> String
Expand description

Get a ZigZag matrix using given string and column-first algorithm.

Two solutions available, use second argument to decide which to use.

§Arguments

  • s - original string to convert.
  • n_rows - total ROWs to layout the characters.

§Examples

use leetcode_rust::problems::p000_0xx::p000_006::zigzag_conversion;
let mut result_value = zigzag_conversion(String::from("PAYPALISHIRING"), 1, None);
assert_eq!(result_value, String::from("PAYPALISHIRING"));
result_value = zigzag_conversion(String::from("PAYPALISHIRING"), 2, None);
assert_eq!(result_value, String::from("PYAIHRNAPLSIIG"));
result_value = zigzag_conversion(String::from("PAYPALISHIRING"), 3, None);
assert_eq!(result_value, String::from("PAHNAPLSIIGYIR"));
