You are given a Singly Linked List of integers. Return true if it has a cycle, else return false.

A cycle occurs when a node's next points back to a previous node in the list.

Example:

In the given linked list, there is a cycle, hence we return true.

Write a program to do basic string compression. For a character which is consecutively repeated more than once, replace consecutive duplicate occurrences with the count of repetitions.

Example:

If a string has 'x' repeated 5 times, replace this "xxxxx" with "x5".
The string is compressed only when the repeated character count is more than 1.

Note:

Consecutive count of every character in the input string is less than or equal to 9. You are not required to print anything. It has already been taken care of. Just implement the given function and return the compressed string.

Bubble Sort is one of the sorting algorithms that works by repeatedly swapping the adjacent elements of the array if they are not in sorted order.

You are given an unsorted array consisting of N non-negative integers. Your task is to sort the array in non-decreasing order using the Bubble Sort algorithm.

For Example:

Bubble Sort implementation for the given array:  {6,2,8,4,10} is shown below :-
