2. Recursively find the maximum and minimum of left part by calling the same function i.e. leftMinMax[2] = minMax(X, l, mid)

## How do you find the minimum and maximum point?

We will set the first derivative of the function to zero and solve for x to get the critical point. If we take the second derivative or f''(x), then we can find out whether this point will be a maximum or minimum. If the second derivative is positive, it will be a minimum value.
