Array Before Last 10

Write a Java program to create an array from a given array of integers. The newly created array will contain the elements from the given array before the last element value of 10.

Sample Solution:

Java Code:

import java.util.*;
public class Exercise104 {
    public static void main(String[] args) {
        int[] array_nums = {11, 15, 13, 10, 45, 20, 33, 53};
        int result = 0; 
        System.out.println("Original Array: "+Arrays.toString(array_nums)); 
        
        int l = 0;
        int[] new_array;

        // Find the first occurrence of 10 in the array
        while(array_nums[l] != 10)
            l++;

        // Create a new array with elements before the first occurrence of 10
        new_array = new int[l];
        for(int i = 0; i < l; i++)
            new_array[i] = array_nums[i];

        System.out.println("New Array: "+Arrays.toString(new_array)); 
    }
}

Sample Output:

Original Array: [11, 15, 13, 10, 45, 20, 33, 53]                       
New Array: [11, 15, 13]
