IN JAVA, USING RECURSION PLEASE
Create a method int[][] generateMatrix(int row, int col, int boundary1, int boundary2, int iteration) that generates a random matrix with random numbers between [min(boundary1, boundary2), max(boundary1, boundary2)).
The sum of the diagonal and the sub-diagonal should be the same. If not, regenerate it again, until a matrix that satisfies the condition is generated (return that matrix).
If you try iteration times and none of the matrixes satisfy the condition, return null.
Using JAVA, write a method that swaps two rows of a two-dimensional array. The row indices to be swapped are passed as parameters to the method (Assume row indices are valid indices). Write a test program to demonstrate correct operation of the method.
Using C++ or Java, compare the bubble sort, inclusion sort, and margesort algorithms.
Make a large array (as large as 1 million) . After adding random numbers to it, record the time and all of the algorithms, record the time once again, and calculate the effective time. For each method, perform this at least 100 times, then calculate the average execution time.

Given an array of unsorted integers, you are requested to investigate whether there exist a pair of numbers in this array that has a sum equal to a given key or not. For example, if the arr = [8, 7, 2, 5, 3] and the key = 12, the answer will be "Yes" as the array has a pair (7 and 5) where their sum = 12 = key, otherwise "No" is returned. To solve this problem, the following idea can be used: i. Consider every pair in the given array and check if their sum = key. ii. Sort the array first, keeping two pointers to on the minimum and maximum of the array and then move from both directions toward the center of the array while checking whether the sum = key or not. Answer the following questions: a) Transform each of the above ideas (i) & (ii) into algorithm (pseudocode) and compute their complexities b) Critic these two ideas: [Which is better?
