I understand the first two bullet points, but the last two (minimum gap and average of even numbers) I'm stuck on.

The program fills a 5x4 array with 20 randomly generated two-digit positive integers so that the first 5 numbers occupy the first column, the next 5 occupy the next column and so on until the fourth column. Make sure that your code generates different random integers when the program is run each time. . Print the array where each element in a row is separated by a space and each row is on its own line. Print the minimum gap between the adjacent elements of each column. For example, if the elements in the first column of the array store 19, 18, 31, 49 and 44 the minimum gap between adjacent elements is 1. For each column in the array, print the average of even numbers. For example, if the elements in the first column of the array store 19, 18, 31, 49 and 44 the average of the even numbers is 31.
