WebTo make a random, unbiased shuffle, you apply the Fisher-Yates algorithm. If you want to shuffle an array x of n elements (numbered from 0 to n -1), you do this: for all i from 0 to n-1 let j = rnd (n - i) + i swap x [i] with x [j] where rnd (k) means: generate a random uniform value in the 0 to k -1 range. Note that it may happen that i = j in ... WebJun 19, 2024 · Consider a three element list.
