write a program that:

a) Inputs a positive integer n from the keyboard where n<=50

If n is out of range then print out an error message and asfk or another input. This process repeats until a valud value for n is ontained.

b) Input two 1D arrays of doubles A and B ( of size n) from the keybord.

c) inputs an integer k(1-3) from the keybord

d) if k=1 then it calculares the average value of A[i] and prints it to the screen.

e) if k=2 then it calculated the maximum value of B[i] and prints it to the screen.

f) if k=3 then it reverses the elements of A and prints A to the screen. (DO NOT INTRODUCE ANOTHER AREAY OR USE ANY LIBRARY FUNCTIONS)

For example: if A=[ 2 7 5 25 10] results in A =[10 25 5 7 2]
