4. The maximum sum subarray problem can be stated as follows. Given an array of n integers, A[0..n - 1], find the maximum sum that can be obtained by adding some number of consecutive elements in the array. If all array elements are negative, the maximum sum is 0 (an empty sum). For example, consider the array with elements: 1, 2, 3, -2, 5, 4, 2,-10, 2, 6 Then the maximum sum that can be formed is 9 by summing the first 5 elements. Give a "brute force" algorithm to solve the maximum subarray sum problem in (n²) operations. Show your analysis.

The goal of this problem is to walk from cell (0, 0) to cell (m, n) of a two-dimensional array. Each step must be either to the right or downward. So you can step from cell (1, 1) to cell (1, 2) or (2, 1). but not from (1, 1) to (0, 1) or (1,0). You are given a toll matrix, where each cell contains a toll that must be paid upon entry into that cell. The goal is to make it from cell (0, 0) to cell (m, n) while paying the smallest possible total toll. Does a greedy algorithm work? Think it out. Write a dynamic programming algorithm that finds the minimum possible total toll. It does not need to do reconstruction and say how to achieve that total toll.
Let A be an array of numbers. In the maximum sub-array problem, your goal is to determine the sub-array A[x . . . y] of consecutive terms for which the sum of the entries is as large as possible. For example, if A = [−2, −3, 4, −1, −2, 1, 5, −3], the maximum sub-array is [4, −1, 2, 1, 5], and the largest possible sum is S = 4 − 1 − 2 + 1 + 5 = 7. Suppose A = [1, 2, −4, 8, 16, −32, 64, 128, −256, 512, 1024, −2048]. Determine S, the largest possible sum of a sub-array of A.
Consider an array arr {12, 14, 17,18, 23, 24, 28, 33, 43). Show using diagram how element 12 can be searched from the array using Binary Search. Also calculate the number of searches needed to find the element 12?
Computer Science Variations on Dynamic Array Consider two operations: INSERT where a single element is inserted into an array with available space INSERT EXPAND where the array is full so in order to insert an element we must copy all the elements of the array into a new array twice as size. Use the accounting ,method to prove that inserting n elements in a dynamic array needs O(n) amortized time.
Array P = [40, 30, 25, 10, 35, 5, 20] Suppose the dimension of 6 matrices (A1, A2 … A6) are given by array P A1 is a P[0] x P[1] matrix A2 is a P[1] x P[2] matrix . . . A6 is a P[5] x P[6] a) Find the minimum number of scalar multiplications necessary to calculate the product of all the 6 matrices (A1.A2.A3.A4.A5.A6) and show the parenthesization for this multiplication. • Solve the problem manually (you need not to write any code) using bottom-up tabulation approach. Compute and show the ‘m’ matrix and ‘s’ matrix to solve your problem.

Given an array A containing N numbers. The problem is to find the minimum gcd among all non-decreasing subarrays. Note: Gcd of k number is the greatest number which divides all k numbers. Example 1: Input : arr[] = {1, 2, 3, 2, 4, 1, 7} Output : 1 Explanation : Some non decreasing subarrays are - {1, 2, 3} gcd = 1, {2, 4} gcd = 2, {1, 7} gcd = 1, minimum gcd = 1

Multiplying Factors For a pair of integers (x,y) and an integer k, the multiplying factor is defined as minimum positive integer m such that LCM(x,y) * m is divisible by k. Here LCM(x,y) represents the smallest positive integer divisible by both x and y, their least common multiple. Given an array arr of n integers and an integer k, find the sum of multiplying factors over all pairs of integers (arr[i], arr[j]) and k0 <= i,j < n. Example Suppose n=3, arr =[4,5,6] and k=12. Pair Multiplying Factor Remarks (4, 3 LCM(4,4)**3=4**3 =12 4 ) LCM(5,5)**12=5** 12=60 (5, 12 LCM(6,6)**2=6**2 5) (6, 2 12 6 )

The ColumnChoice problem takes as input a two-dimensional array A[1..m, 1..n] of Os and 1s with m rows and n columns along with a non-negative integer k < n. It asks whether there exists a subset SC {1, ..., n} of k columns such that for each row i e {1,..., m} there exists at least one column j e S where A[i, j] = 1. Prove that ColumnChoice is NP- complete.
