How can you efficiently find the kth smallest element in an unsorted array of integers? Implement an algorithm in Java to find the kth smallest element using the quickselect algorithm, and explain the time and space complexity of your solution.

Write a java program to print the number from 1 to 100 without using loop, recursion, bitset.Think about arrays and do this with array in O(1) time complexity

Devise an algorithm that detects whether a given array is sorted into ascending order. Write a Java method thatimplements your algorithm. You can use your method to test whether a sort method has executed correctly. Ensure that your program has a test class

Implement a function in Java to find the largest and smallest elements in an array of integers, and return them in a pair. The function should have a time complexity of O(n) and a space complexity of O(1).

Write a Java method that receives a two-dimensional array of primitive ints ( int [] [] ). The array can have any number of rows and any number of items per row. Also, the array can be “ragged” (not all rows have the same number of items). Have the method return the average of all of the items in the array as a primitive double.
