4. Create a vector (name the vector as A) with random 12 values from the interval [1, 40] and use for loop to find the greatest element of the vector (name the element as maxA). Then, use while loop to find the smallest element of the vector (name the element as minA). Define a vector B, where B is the vector A sorted in descending order. Define a vector C, where C is the vector A sorted in ascending order. For the results (output) show the vectors A, B, C, maxA, and minA. [20 points]
