Arrays and queries Given an array A with N integers, perform Q queries. You are given the following types of queries: 1. L X change the value of Ar to X. 2. LRX Find the first index P such that Ap <= X and L
Added by Elena S.
Step 1
- You need to perform \( Q \) queries on this array. - There are two types of queries: 1. `L X`: Change the value of \( A[L] \) to \( X \). 2. `L R X`: Find the first index \( P \) such that \( A[P] \leq X \) and \( L \leq P \leq R \). Show more…

Problem 1: You are given three lists of (distinct) integers, A, B and C. The sizes of these lists are: |A| = n1, |B| = n2, |C| = n3. Let n = n1 + n2 + n3. In each of the arrays, integers are sorted in a descending order (from the largest to the smallest). You need to design an O(log k) time algorithm that finds the k-th largest among all n integers. Show that your algorithm takes O(log k). Hint: use divide-and-conquer.

1) Develop well-documented pseudo code that finds all the elements of a given array (of any size n) that are multiple of x. The code must display the indices and the values of these elements. For instance, given an array A : (22, 61,-10, 21, 0, 9, 50, 17, 35, 81,-46, 19, 5, 77) with x as 5, your code should find and display something similar to the following (notice that this is just an example. Your solution must not refer to this particular example): The elements of the array A that are multiple of 5 are: Index 2 with value -10 Index 6 with value 50 Index 8 with value 35 Index 12 with value 5 a. Briefly justify the motive(s) behind your design. b. What is the Big-O complexity of your solution? Explain clearly how you obtained such complexity. c. What is the Big-Ω complexity of your solution? Explain clearly how you obtained such complexity. d. What is the Big-O space complexity of your solution?
