Question

You are given an unsorted array with n integers. You need to find the third largest integer in the array and print the value. Example: array = [5, 8, 2, 15, 6, 25, 1, 11, 13] Output: 13 array = [9, 3, 14, 22, 1, -6, 18, 15] Output: 15 array = [1, 1, 1, 1, 1] Output: Invalid array = [5, 2] Output: Invalid

Answer 1

Answer:

def get_third_largest(array):

   // this iterates through all the numbers in array 3 times.

   for i in range(2):

       largest_val = float('-inf')

       for val in array:

           if val > largest_val:

               largest_val = val

    // this iterates through the array the third time

   largest_val = float('-inf')

   for val in array:

       if val > largest_val:

           largest_val = val

   if largest_val == float('-inf'):

       largest_val = "invalid"

   print(largest_val)

Explanation:

First of all, I wrote the code above just for you, so you're welcome.

Secondly, there is a lot to it.

What it does is that it iterates through the array 2 times (removing the largest value each time) then the third time it prints the largest value.

But, if the largest value is still float('-inf') otherwise negative of infinity, it will automatically print 'invalid'.

Note: There are shorter ways to do this. If you want you can use a python built-in function that allows you to find the largest value in an array, because I did mine explicitly which makes it kind of longer.
