Find Second Largest Number in an Array (Multiple Approaches)

Given an array of integers, find second largest number in an array. In this tutorial, I have explained a java code to find second highest number in an array without using sorting.

The idea here is to find second largest number in an array using single loop in O(n) time complexity.

Inspired from you even I have started Sharing my Interview Experience with different Mnc's

how to print out two elements in the array if they are both the highest one?

Why you have assigned initial value of largest and second largest with min value

What if we have multiple values example 10 10 10 ??

[navarajpokharel]

i know there comes an extra space but what if i remove repeated array and put in separate array and check if len ==1 then no more second largest element else the second largest element will be a value away from largest element in sorted array

Hi ji, if (arr23[i]!=larges && arr23[i]>secondlargest) {

} what is the logic for this line, without using this also we are getting expected result
