🚀 Programming Example
Deletion from Beginning (Java Program)
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
import java.util.Scanner;
public class DeleteFromBeginning {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int[] arr = new int[100];
int n, i;
System.out.print("Enter number of elements: ");
n = sc.nextInt();
System.out.println("Enter elements:");
for(i = 0; i < n; i++) {
arr[i] = sc.nextInt();
}
// shift elements left
for(i = 0; i < n - 1; i++) {
arr[i] = arr[i + 1];
}
n--;
System.out.println("Array after deletion from beginning:");
for(i = 0; i < n; i++) {
System.out.print(arr[i] + " ");
}
}
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
