Write a program to find the second largest and second smallest number from a 2d array.

Please solve this problem I used to stuck in finding second largest and second smallest. You can do it by C ,C++ or Java I try it pls check it (how to minimize steps) https://code.sololearn.com/cM22IwZ9c18A/?ref=app

Md Saif ali A) since it seems like you dont understand what a set is Ive adjusted the program https://code.sololearn.com/cK2H3qmUH4HN/?ref=app B) like i said thats up to you to decide in such case

Please show your attempt. One ways of solving this task could be sorting the array or 1st determining the min and the max

Lisa can we convert the 2d array into 1 d array say A of size 16( say size of 2d was 4*4) then apply bubble sort(in ascending) and then print A[1] andA[14] as second smallest and largest ? I don't think so finding min and Max will help us .

Lisa and rodwynnejones Is this approach correct? Or you may have alternative [I have displayed each matrix for ease] https://code.sololearn.com/cM22IwZ9c18A/?ref=app

Raul Ramirez 1. inputs to be provided by user. 2. Program fails when a) atleast two largest or smallest number is present b) when all elements are same

Md Saif ali 1. I just made it random for demonstration purposes 2. The program doesnt fail you just need to adjust the ouput in terms of your definition a) idk what you mean b) if all elements are the same by my definition there isnt a 2nd smallest or 2nd largest value There just exist one value

Raul Ramirez 1. Ok I got it 2. a) what will your code print for value {{1,2,3},{7,8,9},{1,9,1}} Will ur code display 2 and 8 for second smallest and largest b)If all elements is same then it is better to display "Not possible" in each case

What if A[1] has the same value as A[0] and A[14] has the same value as A[15]?

I hard coded some values for your 2D array (and some other editing to bypass the user inputs) tested with:- {{1,2,3,4}, {5,6,7,8}, {9, 10, 11, 12}, {13, 14, 15, 16}}; <= works as you intended as the values are unique. {{2,2,3,4}, {5,6,7,8}, {9, 10, 11, 12}, {13, 14, 16, 16,}}; <= second smallest should be 3, but still outputs 2, second largest should be 14, but still outputs 16.
