How to Shuffle an Array in Unity (Randomizing without repeating elements)

// Fisher-Yates shuffle algorithm
private void ShuffleArray ＜T＞ (T[] array)
{
int n = array.Length;
for (int i = n - 1; i＞0; i--)
{
int randIndex = Random.Range(0, i + 1);
T temp = array[i];
array[i] = array[randIndex];
array[randIndex] = temp;
}
}
