“while” loop:

A while loop is a control flow statement whose basic purpose is to execute the block of statements repeatedly as long as the conditional statement is true.

If the condition is false then it does not execute the block of statement.

Insertion sort algorithm:

The algorithm is basically designed to organize and sort the array or list of elements in specific manner, that enables the system and user to get the final sorted array or a list of elements.

Generally, the insertion sort technique divides the list into two parts: sorted or unsorted list.

In the sorted list, the method assumes that one element of the list is already sorted and then it performs the operation on the unsorted list by inserting elements in its appropriate position in the sorted list.

def eliminate_neighbours (items): Given the sequence of integer items that are guaranteed to be some permutation of positive integers from 1 to n where n is the length of the list, find the smallest number among those that still remain in the list, and remove from the list both that number and whichever of its current immediate neighbours is larger. The function should repeat this basic operation until the largest number in the original list gets eliminated. Return the number of removal operations that were needed to achieve this goal. For example, given the list [5, 2, 1, 4, 6, 31, the operation would remove element 1 and its current larger neighbour 4, resulting in the list [5, 2, 6, 3]. Applied again, that operation would remove 2 and its current larger neighbour 6, thus reaching the goal in two steps. items Expected result [1, 6, 4, 2, 5, 3] 1 [8, 3, 4, 1, 7, 2, 6, 5] 3 [8, 5, 3, 1, 7, 2, 6, 4] 4 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] 5 range (1, 10001) 5000 [1000] + list(range (1, 1000))…

Q2: a. Write an algorithm that searches a sorted list of n items by dividing it into three sublists of almost n/3 items. This algorithm finds the sublist that might contain the given item and divides it into three smaller sublists of almost equal size. The algorithm repeats this process until it finds the item or concludes that the item is not in the list. Dry run the above algorithm to find the value 240. A[] = {10,15,20,60,65,110,150,220,240,245,260,290,300,460,470,501}
