print random array elements without duplication

How can i can print the elements of an array in an random order without printing the same element twice? Do you have a code/function for that? i struggle figuring it out.

try to implement this logic: 1) keep a list of previously printed elements 2) generate random index of the array where the elements are stored 3) if the number in the selected index does NOT appear in the previously printed elements list, add it to the list and print it 4) if the elements list and previously printed elements list are of same length, return (program ended) 5) else, go back to step 2
