Java Day 6: Let's Review
Given a string, S , of length N that is indexed from 0 to N-1, print its even-indexed and odd-indexed characters as 2 space-separated strings on a single line (see the Sample below for more detail).
Note: 0 is considered to be an even index.
- import java.io.*;
- import java.util.*;
-
- import java.util.Scanner;
-
- public class Solution {
- public static void main(String[] args) {
- Scanner in = new Scanner(System.in);
- int N = in.nextInt();
-
- in.nextLine();
-
- for (int i = 0; i < N; i++) {
- String string = in.nextLine();
- char[] charArray = string.toCharArray();
-
- for (int j = 0; j < charArray.length; j++) {
- if (j % 2 == 0) {
- System.out.print(charArray[j]);
- }
- }
-
- System.out.print(" ");
-
- for (int j = 0; j < charArray.length; j++) {
- if (j % 2 != 0) {
- System.out.print(charArray[j]);
- }
- }
-
- System.out.println();
- }
-
- in.close();
- }
- }
