Reverse the array
Easy
Asked in companies
Given an array with N elements, the task is to reverse all the array elements and print the reversed array.
Input Format:
The first line contains an integer N representing the size of the array.
The second line contains N space-separated integers representing the elements of the array.
Output Format:
The only line of the output prints N space-separated integers representing the Reversed array elements.
Constraints:
1 <= N <= 10^3
1 <= arr[i] <= 10^9
1 <= K < N
Approaches
- Initialise start and end indices with start = 0, end = N-1 where N is the total number of elements in array.
- We then run a loop while start < end and swap arr[start] with arr[end].
- Finally, we increment start and decrement end variable
