write 2 methods named descBubbleSort() and descInsertionSort() that take an array

of Strings as an argument and sort the string values in a descending order using

bubble sort and insertion sort respectively. 

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3
30 10 2
5 11 15

Given two strings(S1 and S2), write a program to determine if a string S2 is a rotation of another string S1.

For example, if the given strings S1 and S2 are "python" and "onpyth",

The first right rotation of s1 is "npytho" which is not equal to string S2"onpyth"

The second right rotation of s2 is "onpyth" which is equal to string S2 "onpyth".

So the output should be 2
