Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves, calls itself for the two halves and then merges the two sorted halves. The merge () function is used for merging two halves. The merge (arr, l, m, r) is key process that assumes that arr [l..m] and arr [m+1..r] are sorted and merges the two sorted sub-arrays ...Merge Sort is a Divide and Conquer algorithm.

The general syntax for list comprehension looks like this: new_list = [expression for variable in iterable] Let's break it down: List comprehensions start and end with opening and closing square brackets, [].Find largest number in list using For loop. Though finding the largest number using sort () function is easy, using Python For Loop does it relatively faster with less number of operations. Also, the contents of the list are unchanged. Python Program. a = [18, 52, 23, 41, 32] # Variable to store largest number.In the above example, we first convert the list into a set, then we again convert it into a list. Set cannot have a duplicate item in it, so set() keeps only an instance of the item.
