Given a list of numbers, the task is to write a Python program to find the second largest number in given list.
Input: list1 = [10, 20, 4] Output: 10 Input: list2 = [70, 11, 20, 4, 100] Output: 70
Method 1: Sorting is an easier but less optimal method. Given below is an O(n) algorithm to do the same.
Second highest number is : 45
Method 2: Sort the list in ascending order and print the second last element in the list.
Second largest element is: 45
Method 3: By removing the max element from the list
Method 4: Find max list element on inputs provided by the user
Enter number of elements in list: 4 Enter elements: 12 Enter elements: 19 Enter elements: 1 Enter elements: 99 Second Largest element is: 19
