Compress the String

 

Write a program to do basic string compression. For a character which is consecutively repeated more than once, replace consecutive duplicate occurrences with the count of repetitions.

Sample Input 1:
aaabbccdsa
Sample Output 1:
a3b2c2dsa
import java.util.Scanner;

public class CompressString {

	public static void main(String[] args) {
		Scanner s = new Scanner(System.in);
		String st = s.nextLine();
		String c = getCompressedString(st);
		System.out.println(c);

	}
	public static String getCompressedString(String str) {

		String s="";
		int l=str.length();
		for(int i=0;i<l;i++)
		{

				// Count occurrences of current character 
				int count = 1; 
				while (i < l - 1 &&  str.charAt(i) == str.charAt(i + 1)) 
				{ 
					count++; 
					i++; 
				} 

				if (count == 1)
				{
					 s=s+str.charAt(i);
				  
				} 
				
				else 
				{
					s=s+str.charAt(i)+count;
				}
		} 
	
		return s;
	}
}

Minimum Length Word

  Given a string S (that can contain multiple words), you need to find the word which has minimum length. Sample Input 1 : this is test string Sample Output 1 : is public class Solution { public static String minLengthWord(String input){ String[] arr=input.split(" "); int i=0; int minlength; minlength=Integer.MAX_VALUE; String smallest; smallest = ""; for(i=0;i<arr.length;i++) { if(arr[i].length() < minlength) { smallest=arr[i]; minlength=arr[i].length(); } } return smallest; } }

Check Number Sequence

  You are given S, a sequence of n integers i.e. S = s1, s2, ..., sn. Compute if it is possible to split S into two parts : s1, s2, ..., si and si+1, si+2, ….., sn (0 <= i <= n) in such a way that the first part is strictly decreasing while the second is strictly increasing one. Note : We say that x is strictly larger than y when x > y. So, a strictly increasing sequence can be 1 4 8. However, 1 4 4 is NOT a strictly increasing sequence. That is, in the sequence if numbers are decreasing, they can start increasing at one point. And once the sequence of numbers starts increasing, they cannot decrease at any point further. Sequence made up of only increasing numbers or only decreasing numbers is a valid sequence. So, in both the cases, print true. You just need to print true/false. No need to split the sequence. Sample Input 1 : 5 9 8 4 5 6 Sample Output 1 : true import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner s = new Scanner (Sys
