• improved the time complexity of ArrayQueueDequeue from O(n) to O(1)
• observed huge optimisation on BenchmarkArrayQueueDequeue100000 by over 2757% time for each operation

[yashwanth-reddy909]

existing dequeue method calling Remove(0) function of arraylist which removes the zero index element of the slice using slices.Delete which it does is

s = append(s[:i], s[j:]...)

updated it to this s = s[1:]
