Array Reversal


Problem Statement :


Given an array, of size n, reverse it.

Example: If array, arr=[1.2.3.4,5] after reversing it, the array should be, arr=[5,4,3,2,1]


Input Format:

The first line contains an integer, n, denoting the size of the array. The next line contains n space-separated integers denoting the elements of the array.


Constraints:
1<=n<=1000
1<=arr[i]<=1000, where  is the  element of the array.


Output Format:

The output is handled by the code given in the editor, which would print the array.

                            Solution in C :

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num, *arr, i;
    scanf("%d", &num);
    arr = (int*) malloc(num * sizeof(int));
    for(i = 0; i < num; i++) {
        scanf("%d", arr + i);
    }

    for(i = num-1; i>-1; i--)
        printf("%d ", *(arr + i));
        
    return 0;
}

Queue using Two Stacks

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que
