Python program to find second largest number in a list
Output 45 The time complexity of the code is O nlogn where n is the number of elements in the list This is because the numpy argsort function has a time complexity of O nlogn for sorting the input list and selecting the second largest element from the sorted list takes constant time
Program to Find Second Largest Number in Python Scaler, There are many approaches to finding the second largest number in Python Some of the approaches are mentioned below By sorting the list and then printing the second largest element By removing the maximum element By traversing the entire list By using a max heap Now we will discuss all the methods one by one
Python program to find second largest number in a list
By removing the maximum number and then using max function to get the second largest number By using the Brute force approach Let us look at each approach in detail Approach 1 Find Second Largest In this approach we will first sort the elements of the list For sorting the list we will use the predefined sort function in Python
