Assume that someone dictates you a sequence of numbers and you need to write it down. for brevity, he dictates it as follows: first says the number of consecutive identical numbers and then says the number itself. e. g. the sequence 1 1 3 3 3 2 2 2 2 14 14 14 11 11 11 2 will be dictated as "two one, three three, four twos, three fourteens, three elevens, one two", so you will write down the sequence 2 1 3 3 4 2 3 14 3 11 1 2. the challenge is to write the program which compresses the given sequence using this approach. input: your program should read lines from standard input. each line is a sequence of l integers, where each integer is n, separated by a whitespace. n is in range [0, 99]. l is in range [1, 400]. output: for each test case, produce a single line of output containing a compressed sequence of numbers separated by a single space char.

We have the following code in python with appropriate comments

Explanation:

line = input("Enter your line of integers: ")

# Splits at space

intList = line.split()

#initializing the count to 1

count = 1

#initializing the count to empty string

output = ''

#iterating over the list

for index, x in enumerate(intList):

#handling last index separately

if index == len(intList)-1:

if intList[index] == intList[index-1]:

output = output + str(count) + ' ' + str(intList[index])

else:

count = 1

output = output + str(count) + ' ' + str(intList[index])

#handling indexes other than the last index    

else:

if intList[index]==intList[index+1]:

count = count + 1 #if next integer is same, we increase the count by 1

else:

output = output + str(count) + ' ' + str(intList[index]) + ' '

count = 1

print(output)

Below is the program

Explanation:

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.nio.charset.StandardCharsets;

import java.util.HashMap;

import java.util.Map;

import java.io.File;

import java.util.Scanner;

import java.util.LinkedHashMap;

public class Main {

 /**

  * Iterate through each line of input.

  */

 public static void main(String[] args) throws IOException {

   InputStreamReader reader = new InputStreamReader(System.in, StandardCharsets.UTF_8);

   BufferedReader in = new BufferedReader(reader);

   int number = 0;

   int numberOfParagraph = 0;

   int numberOfSequence = 1;

   char ch;

   HashMap<Integer, Integer> map = new HashMap<>();

   String line;

   while ((line = in.readLine()) != null) {

     if(line.equals('\n'))

     {

       numberOfParagraph++;

     }

     if(numberOfParagraph < 1 || numberOfParagraph > 400)

     {

       break;

     }

     for (int index = 0; index < line.length(); index++)

     {

        //number = line.parseInt(line);

        ch = line.charAt(index);

        number = ch - '0';

        if(number < 0 || number > 99)

        {

          continue;

        }

        if(!map.containsKey(number))

        {

          map.put(number, 1);

        }

        else

        {

          numberOfSequence++;

          map.put(number, numberOfSequence);

        }

     }

     //System.out.println(line);

   }

    for (Map.Entry<Integer, Integer> entry : map.entrySet()) {

       System.out.println(entry.getKey() + " ocurrs " + entry.getValue()+ " times");

   }

 }

}
