Reverse Strings

The video tutorial discusses the problem of reversing a string given as an array, with the constraint of not using extra space. It begins with an introduction to the problem and its constraints, followed by a discussion of an initial solution that uses extra space, which is not suitable due to the problem's constraints. The tutorial then introduces an efficient two-pointer solution that reverses the string in place, meeting the space complexity requirement. The video concludes with a detailed code walkthrough of the two-pointer method, explaining each step and the logic behind it.
