4. Bucket: Bucket sorts a slice. It is mainly useful when input is uniformly distributed over a range.
5. Cocktail: Cocktail sort is a variation of bubble sort, operating in two directions (beginning to end, end to beginning)
6. Comb: Comb is a simple sorting algorithm which is an improvement of the bubble sorting algorithm.
7. Count: No description provided.
8. Cycle: Cycle sort is an in-place, unstable sorting algorithm that is particularly useful when sorting arrays containing elements with a small range of values. It is theoretically optimal in terms of the total number of writes to the original array.
9. Exchange: No description provided.
10. HeapSort: No description provided.
11. ImprovedSimple: ImprovedSimple is a improve SimpleSort by skipping an unnecessary comparison of the first and last. This improved version is more similar to implementation of insertion sort
12. Insertion: No description provided.
13. Merge: Merge Perform merge sort on a slice
14. MergeIter: No description provided.
15. Pancake: Pancake sorts a slice using flip operations, where flip refers to the idea of reversing the slice from index 0 to i.
16. ParallelMerge: ParallelMerge Perform merge sort on a slice using goroutines
17. Partition: No description provided.
18. Patience: No description provided.
19. Pigeonhole: Pigeonhole sorts a slice using pigeonhole sorting algorithm. NOTE: To maintain time complexity O(n + N), this is the reason for having only Integer constraint instead of Ordered.
20. Quicksort: Quicksort Sorts the entire array
21. QuicksortRange: QuicksortRange Sorts the specified range within the array
22. RadixSort: No description provided.
23. Selection: No description provided.
24. Shell: No description provided.
25. Simple: No description provided.

Package xor is an encryption algorithm that operates the exclusive disjunction(XOR) ref: https://en.wikipedia.org/wiki/XOR_cipher

Functions:

1. Decrypt: Decrypt decrypts with Xor encryption
2. Encrypt: Encrypt encrypts with Xor encryption after converting each character to byte The returned value might not be readable because there is no guarantee which is within the ASCII range If using other type such as string, []int, or some other types, add the statements for converting the type to []byte.
3. FuzzXOR: No description provided.
