- Take an array of length n where all the numbers are nonnegative and unique. Find the element inthe array possessing the highest value. Split the element into two parts where the first part containsthe next highest value in the array and the second part holds the required additive entity to get thehighest value. Return the array index value. Consider the negative numbers as well.Input: [4, 8, 6, 3, 2]Output: [4, 6, 2, 6, 3, 2]Suppose an array sorted in ascending order is rotated at some pivot unknownto you beforehand.

- You are given two arrays, one shorter (with all distinct elements) and onelonger. Find the shortest subarray in the longer array that contains all the elements in the shorterarray. The items can appear in any order.EXAMPLEInput:{1, 5, 9}{7, 5, 9, 0, 2, 1, 3, 5. 7, 9. 1, 1, 5, 8, 8, 9, 7}Output:[7, 10] (the underlined portion above): In an array of integers, a "peak" is an element which is greater than or equal tothe adjacent integers and a "valley" is an element which is less than or equal to the adjacent integers. For example, in the array {5, 8, 6, 2, 3, 4, 6}, {8, 6} are peaks and {5, 2} are valleys. Given an arrayof integers, sort the array into an alternating sequence of peaks and valleys.EXAMPLEInput: {5, 3, 1, 2, 3}Output: {5, 1, 3, 2, 3}You are given two arrays, one shorter (with all separate items) and one longer (with no unique elements). Find the shortest subarray in the larger array that contains all of the shorter array's items. The things can be shown in any order.EXAMPLEInput: {1, 5, 9}{7, 5, 9, 0, 2, 1, 3, 5. 7, 9. 1, 1, 5, 8, 8, 9, 7}Results: [7, 10] (the underlined portion above)
- Given a sorted array of n integers that has been rotated an unknownnumber of times, write code to find an element in the array. You may assume that the array wasoriginally sorted in increasing order.EXAMPLElnput:find5in{15, 16, 19, 20, 25, 1, 3, 4, 5, 7, 10, 14}Output: 8 (the index of 5 in the array Given a sorted array of n integers that has been rotated an unknownnumber of times, write code to find an element in the array. You may assume that the array wasoriginally sorted in increasing order.EXAMPLElnput:find5in{15, 16, 19, 20, 25, 1, 3, 4, 5, 7, 10, 14}Output: 8 (the index of 5 in the arrayGiven a sorted array of n integers that has been rotated an unknownnumber of times, write code to find an element in the array. You may assume that the array wasoriginally sorted in increasing order.EXAMPLElnput:find5in{15, 16, 19, 20, 25, 1, 3, 4, 5, 7, 10, 14}Output: 8 (the index of 5 in the array)You are given an array called source, with length n, and a set of m arrays called target, each also with length n. The arrays contain only positive integers. The arrays are unsorted. For any number x, the smallest number in target[x] is guaranteed to be smaller than target[x+1]. All the numbers in target are unique. The following figure illustrates an example of valid source and target arrays for this case, where n=5 and m=6. source = [14, 13, 15, 11, 12]target[0] = [4, 2, 1, 3, 5]target[1] = [6, 8, 7, 10, 9]target[2] = [14, 15, 12, 11, 13]target[3] = [17, 20, 16, 18, 19]target[4] = [22, 21, 24, 23, 25]target[5] = [30, 29, 28, 27, 26] The smallest number in each array in target is styled with bold. You can quickly see that the smallest number in target[0] is smaller than the smallest number in target[1], the smallest number in target[1] is smaller than the smallest number in target[2], and so on. You can also see that there is no duplicate number within the arrays in target. You are…
