Given an input string
N
consisting of numerals and separators (, ) in the Indian Numeric System, the task is to print the string after placing separators(, ) based on International Numeric System.
Examples:
Input: N = “12, 34, 56, 789” Output: 123, 456, 789 Input: N = “90, 05, 00, 00, 000” Output: 90, 050, 000, 000
Approach:
- Remove all the separators (, ) from the string.
- Iterate from the end of the string and place a separator(, ) after every third number.
- Print the result.
Below is the implementation of the above approach:
C++
// C++ Program to convert// the number from Indian system// to International system#include <bits/stdc++.h>using namespace std;// Function to convert Indian Numeric// System to International Numeric Systemstring convert(string input){ // Length of the input string int len = input.length(); // Removing all the separators(, ) // From the input string for (int i = 0; i < len; i++) { if (input[i] == ',') { input.erase(input.begin() + i); len--; i--; } } // Initialize output string string output = ""; int ctr = 0; // Process the input string for (int i = len - 1; i >= 0; i--) { ctr++; output = input[i] + output; // Add a separator(, ) after // every third digit if (ctr % 3 == 0 && ctr < len) { output = ',' + output; } } // Return the output string back // to the main function return output;}// Driver Codeint main(){ string input1 = "12,34,56,789"; string input2 = "90,05,00,00,000"; cout << convert(input1) << endl; cout << convert(input2) << endl;} |
Java
public class IndianToInternationalConversion { // Function to convert Indian Numeric // System to International Numeric System static String convert(String input) { // Remove all the separators (, ) from the input string input = input.replaceAll(",", ""); // Initialize the output string and counter StringBuilder output = new StringBuilder(); int ctr = 0; // Process the input string from right to left for (int i = input.length() - 1; i >= 0; i--) { ctr++; output.insert(0, input.charAt(i)); // Add the current digit to the output // Add a separator (, ) after every third digit (from right to left) if (ctr % 3 == 0 && ctr < input.length()) { output.insert(0, ','); } } // Return the output string return output.toString(); } // Driver Code public static void main(String[] args) { String input1 = "12,34,56,789"; String input2 = "90,05,00,00,000"; System.out.println(convert(input1)); System.out.println(convert(input2)); }} |
Python
# Function to convert Indian Numeric# System to International Numeric Systemdef convert(input_str): # Length of the input string len_input = len(input_str) # Removing all the separators (, ) # From the input string i = 0 while i < len_input: if input_str[i] == ',': input_str = input_str[:i] + input_str[i+1:] len_input -= 1 else: i += 1 # Initialize output string output = "" ctr = 0 # Process the input string for i in range(len_input - 1, -1, -1): ctr += 1 output = input_str[i] + output # Add a separator (, ) after # every third digit if ctr % 3 == 0 and ctr < len_input: output = ',' + output # Return the output string back # to the main function return output# Driver Codeif __name__ == "__main__": input1 = "12,34,56,789" input2 = "90,05,00,00,000" print(convert(input1)) print(convert(input2)) |
Javascript
// Function to convert Indian Numeric// System to International Numeric Systemfunction convert(input) { // Removing all the separators(, ) // From the input string input = input.replace(/,/g, ''); // Initialize output string let output = ''; let ctr = 0; // Process the input string for (let i = input.length - 1; i >= 0; i--) { ctr++; output = input.charAt(i) + output; // Add a separator(, ) after // every third digit if (ctr % 3 === 0 && ctr < input.length) { output = ',' + output; } } // Return the output string back // to the caller return output;}// Driver Codeconst input1 = '12,34,56,789';const input2 = '90,05,00,00,000';console.log(convert(input1));console.log(convert(input2)); |
Output
123,456,789 90,050,000,000
