1. Generate any number of random integers between 20 and 100 from the uniform distribution [ 3 points].
2. Write a function to do the following:

• • Accept just one integer vector as an input parameter [2 points].
  • Perform the rest of the operations only if the input is an integer vector with at least ONE element. If not, return NA [4 points].
  • Return ONE numeric vector (numbers with 2 decimal places) [1 point].
  • Run a loop on the input vector to perform the following calculations to generate the final vector [10 points].
    • If the index is even, the output is the square of the number.
    • If the index is odd, the output is the square root of the number.
