Create a different version of the same program that uses functions. Write the function randNumArr() that takes a number indicating how many numbers there should be, and a number indicating the limit (from zero to this limit). In other words, randNumArr(20, 1000) should return an array with 20 random numbers under 1000. Then create a function called min() that takes an array of numbers and returns the smallest number in the array. Your min() function is not allowed to use Math.min(). Instead it should use a loop to go through the array and find the smallest number.
