Given an array arr[] of N elements which are in range [0, 9]. the task is to convert each array element into its numeric strings.
Examples:
Input: arr[] = [1, 4, 3, 2, 6]
Output: one four three two sixInput: arr[]= [0, 4, 4, 6, 9]
Output: zero four four six nine
Approach: The problem can be solved with the help of map. Follow the steps given below:
- Map each number from 1 to 9 to their respective numeric strings.
- Iterate through the array and change each number to the string to which it is mapped.
Below is the implementation of the above approach.
C++
// C++ code to implement the approach #include <bits/stdc++.h> using namespace std; // Function to convert // the numeric array to words void convert( int arr[], int N) { map< int , string> mp; int i; // Map the integers to // their respective numeric string mp[0] = "zero" ; mp[1] = "one" ; mp[2] = "two" ; mp[3] = "three" ; mp[4] = "four" ; mp[5] = "five" ; mp[6] = "six" ; mp[7] = "seven" ; mp[8] = "eight" ; mp[9] = "nine" ; // Traverse array elements and print for (i = 0; i < N; i++) cout << mp[arr[i]] << " " ; cout << endl; } // Driver Code int main() { int arr[] = { 1, 4, 3, 2, 6 }; int N = sizeof (arr) / sizeof (arr[0]); // Function call convert(arr, N); return 0; } |
Java
// JAVA code to implement the approach import java.util.*; class GFG { // Function to convert // the numeric array to words public static void convert( int arr[], int N) { HashMap<Integer, String> mp = new HashMap<>(); int i; // Map the integers to // their respective numeric string mp.put( 0 , "zero" ); mp.put( 1 , "one" ); mp.put( 2 , "two" ); mp.put( 3 , "three" ); mp.put( 4 , "four" ); mp.put( 5 , "five" ); mp.put( 6 , "six" ); mp.put( 7 , "seven" ); mp.put( 8 , "eight" ); mp.put( 9 , "nine" ); // Traverse array elements and print for (i = 0 ; i < N; i++) System.out.print(mp.get(arr[i]) + " " ); System.out.println(); } // Driver Code public static void main(String[] args) { int arr[] = new int [] { 1 , 4 , 3 , 2 , 6 }; int N = arr.length; // Function call convert(arr, N); } } // This code is contributed by Taranpreet |

C#
// C# code to implement the approach using System; using System.Collections.Generic; class GFG { // Function to convert // the numeric array to words static void convert( int []arr, int N) { Dictionary< int , string > mp = new Dictionary< int , string >(); int i; // Map the integers to // their respective numeric string mp[0] = "zero" ; mp[1] = "one" ; mp[2] = "two" ; mp[3] = "three" ; mp[4] = "four" ; mp[5] = "five" ; mp[6] = "six" ; mp[7] = "seven" ; mp[8] = "eight" ; mp[9] = "nine" ; // Traverse array elements and print for (i = 0; i < N; i++) Console.Write(mp[arr[i]] + " " ); Console.WriteLine(); } // Driver Code public static void Main() { int []arr = { 1, 4, 3, 2, 6 }; int N = arr.Length; // Function call convert(arr, N); } } // This code is contributed by Samim Hossain Mondal. |
Javascript
<script> // JavaScript code to implement the approach // Function to convert // the numeric array to words const convert = (arr, N) => { let mp = {}; let i; // Map the integers to // their respective numeric string mp[0] = "zero" ; mp[1] = "one" ; mp[2] = "two" ; mp[3] = "three" ; mp[4] = "four" ; mp[5] = "five" ; mp[6] = "six" ; mp[7] = "seven" ; mp[8] = "eight" ; mp[9] = "nine" ; // Traverse array elements and print for (i = 0; i < N; i++) document.write(`${mp[arr[i]]} `); document.write( "<br/>" ); } // Driver Code let arr = [1, 4, 3, 2, 6]; let N = arr.length; // Function call convert(arr, N); // This code is contributed by rakeshsahni </script> |
Output
one four three two six
Time Complexity: O(N).
