Java: Restore the original string by entering the compressed string with this rule
Java Basic: Exercise-238 with Solution
When characters are consecutive in a string, it is possible to shorten it by replacing them with a certain rule. For example, the character string YYYYY, if it is expressed as # 5 Y, it is compressed by one character.
Write a Java program to restore the original string by entering the compressed string with this rule.
However, the # character does not appear in the restored character string.
Note: The original sentences are uppercase letters, lowercase letters, numbers, symbols, less than 100 letters, and consecutive letters are not more than 9 letters.
Input:
Multiple character strings are given. One string is given per line.
Output: The restored character string for each character on one line.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public static void main(String[] args)
{
Scanner stdIn = new Scanner(System.in);
System.out.println("Input the text:");
String str = stdIn.next();
for(int i = 0; i < str.length(); ++i)
{
if(str.charAt(i) == '#')
{
for(int j = 0; j < (str.charAt(i + 1) - '0'); ++j)
{
System.out.print(str.charAt(i + 2));
}
i += 2;
}
else
{
System.out.print(str.charAt(i));
}
}
System.out.println();
}
}
Sample Output:
Input the text: XY#6Z1#4023 XYZZZZZZ1000023
