How To Reverse An Array | Multiple Approaches | C++ | Optimal Approach - Swapping | 2 Pointers

In this video, we will solve the problem of reversing the elements in the given array, irrespective of the data type of the elements present, via an optimal approach of swapping elements.

We will also look at the C++ code for the optimal approach and C++ inbuilt function to reverse the array, i.e., reverse().

This is the first problem of love Babbar's 450 sheet from the array section.
