- VelTech Codeathon Jan Finals Test will be Lowest Common Multiple (LCM) You are given an array of positive integers, arr, of size array length. You are asked to build set S which consists of the LCM of every pair of adjacent elements in arr. Your task is to find the largest element in set S For example, for the array (1, 2, 3, 4), set S = { Icm(1,2), Icrm(2,3), Icrm(3,4) } = (2, 6, 12). The largest element is Fill you 12 Notes The array contains only positive integers. Adjacent elements may NOT be circular, ie. they may not wrap around the end of the array Definition of LCM A multiple of a number, num, is a number that can be divided by num. For example, the multiples of 5 are 5, 10, 15, 20, 25, and so on, The lowest common multiple (LCM) of two numbers, a and b, is the smallest positive number that is a multiple of both a and b Example 1 Input 4 1324 Output 9.

- 6 - Merge sorted arrays Program a method merge_sorted(a,b) that when given two sorted arrays a and b, returns a new sorted array c that has the elements from array a and array b. For example when given = [1,3,5,6,10] a b = [1,4,6,8] %3D the resulting array should be: C = = [1,1,3,4,5,6,6,8,10] This method should not call a sorting method. Instead, the resulting array should be produced by "zipping" the two input arrays together: we repeatedly select the least element that we did not consider before from a and b and include this in c. For example: a = [1,3,5,6,10] b = [1,4,6,8] C = [1,1,3, ...] the arrows (^) point to the lowest element we did not consider before. Of these, element 4 from b is less than element 5 from a. For this reason, we select 4 as the next element and advance the arrow ^ for b to point to 6.19. Binary Search Implementation Below is an implementation of binary search, but the implementation contains an error. What is the error? 251 def binary_search(array, target): 252 left,right = 0,len(array)-1 while left <= right: mid = left + ((right - left) // 2) if target == array[mid]: 253 254 255% 256 return mid elif target < array[mid]: left = mid + 1 257 258 259 else: 260 right = mid - 1 261 return None Pick ONE option Line 253 should be change to: while left < right Lines 258 and 260 should be switched right should be initialized to len(array) instead of len(array)-1 Nothing is incorrect Clear SelectionLab 16 Implementing bubble sort In this lab, you will implement the bubble sort algorithm. The bubble sort is so called because it compares adjacent items, "bubbling" the smaller one up toward the beginning of the array. By comparing all pairs of adjacent items starting at the end of the array, the smallest item is guaranteed to reach the beginning of the array at the end of the first pass. The second pass begins again at the end of the array, ultimately placing the second smallest item in the second position. During the second pass, there is no need to compare the first and second items, because the smallest element is guaranteed to be in the first position. Bubble sort takes at most n - 1 passes for an array of n items. During the first pass, n - 1 pairs need to be compared. During the second pass, n - 2 pairs need to be compared. During the ith pass, n - i pairs need to be compared. During the last pass, n - (n - 1) or one pair needs to be compared. If, during any pass, no two…
