Let A be an array containing n numbers (positive and negative). Develop a divide and conquer algorithm that finds the two indices 1 sisjsn such that A[k] (the sum of the elements from i to j) is maximized. For example, in the array A [10,-5,-6,5, 7,-2,4, -11], the sub-array A[4:6] has the sum 5+ 7-2+4-14 and no other sub-array contains elements that sum to a value greater than 14, so for this input the...

Let A be an array of N distinct positive numbers such that at most sqrt(N) of them is larger than N. Ex: if N=100, there are at most 10 elements in A that are greater than 100. 1. Split A into A1 and A2 such that A1 contains the elements greater than N and A2 contains the remaining elements. Do this in O(N) 2. Sort A1 in O(N) 3. Sort A2 in O(N) 4. Sort A in O(N) I don't...

Write a C program convert.c that converts each number in an array by the sum of that number plus 6 modulus 10. A sample input/output: Enter the length of the array: 5 Enter the elements of the array: 3 928 4 14 77 Output: 9 4 0 0 3 The program should include the following function: void convert(int *a1, int n, int *a2) The function converts every element in array a1 of length n to an output array a2. The...

A method called linearSearch(), which takes as parameters an array of int followed by three values of type int, and returns a value of type int. The first int parameter represents a key, the second int parameter represents a starting position, and the third int parameter represents an end position. If the key occurs in the array between the start position (inclusive) and the end position (exclusive), the method returns the position of the first occurrence of the key in...

Consider the Java program below to sort an array A in an ascending order. M, N, and K are positive integers, and A is an array of N nonnegative integers where 0 < A[i] < M for all i e {0,..., N -1}. In this program, list is a class of an integer list with the following methods. 1st.size(): returns the number of elements in the list lst 1st.get(i): returns the element at the i-th position in the list lst...
