2024年12月1日 · The article outlines various methods to find the second largest number in a list, including using loops, sorting, and the heapq.nlargest() function.

In this article, we will write a Python program to find the second largest element in a given array. Example. Input: arr[] = {2, 42, 13, 64, 1} Output: 42 Input: arr[] = {2, 3, 4, 5, 5} Output: 4 Input: arr[] = {2, 2, 2} Output: There is no second largest element in the given array. We will solve this problem using two strategies.

2025年2月10日 · # Python program to find second largest element in an array # using Sorting def getSecondLargest (arr): n = len (arr) # Sort the array in non-decreasing order arr. sort # start from second last element as last element is the largest for i in range (n-2,-1,-1): # return the first element which is not equal to the # largest element if arr [i ...

2024年3月6日 · Print the biggest number in the array by accessing the first element of the sorted array using arr1 [0]. Print a message indicating that the biggest number in the array has been found. Time Complexity : O (n) Auxiliary Space : O (1) Find Largest Element with Python Lambda. In this program, we have an array called array with some elements.

2019年11月25日 · Here is the code to find the 2nd largest number in the list without using any inbuilt functions. data = [11,22,1,2,5,67,21,32] max1 = data[0] # largest num max2 = data[1] # second largest num for num in data: if num > max1: max2 = max1 # Now this number would be second largest max1 = num # This num is largest number in list now.

Write a Python Program to Find the second Largest Number in a Numpy Array. We used the numpy sort function to sort the array in ascending order. Next, we print the value at the last but one index position. This Program helps to Find the Second Largest in the numpy Array using the For Loop range. if (secLarr[i] > first): second = first.

2020年11月22日 · In this tutorial, you will learn how to write Python program to find second largest number in an array. To find the second largest element, First sort the given array in ascending order. Then select the second last element from the list.

2024年9月30日 · One straightforward way to find the second largest element is to sort the array and then access the second last element. Here’s how you can do it: # Remove duplicates. unique_arr = list(set(arr)) # Sort the array in descending order. unique_arr.sort(reverse=True) # Return the second largest element.

2025年1月5日 · import java.util.*; public class SecondLargestSingleTraversal { public static void findSecondLargest(int[] arr) { if (arr.length < 2) { System.out.println("No second largest number"); return; } int largest = Integer.MIN_VALUE; int secondLargest = Integer.MIN_VALUE; for (int num : arr) { if (num > largest) { secondLargest = largest; largest ...

2021年7月1日 · Approach to find second largest number in a list. For executing this program in Python, there are multiple approaches we can follow: By sorting the list and printing the second maximum element. By removing the maximum number and then using max() function to get the second-largest number. By using the Brute-force approach.
