Question

https://code.sololearn.com/cs1TEXrLkRWF/?ref=app

So It is like this -
[4,5,5,4]

It took 2 index -5
Then it took 3 index - 5

10/2 = 5 so Output should be 5 instead of 4.5

Please Explain it.
Thank You in Advance.

Answer 1

You sorted the list I guess?

Answer 2

Balraj Singh no,your code first took the a first index which is 4, and a second index which is 5 , it added that and divided it by 2.

Which is ofcourse 4.5

the sorted list was [4,4,5,5] . in your code first iteration was skipped,then the second 4 becomes the first index,and 5 becomes the second index

Answer 3

That's your list: (4,5,5,4)
Sort it => (4,4,5,5)
Median = (4 + 5) / 2 = 4.5

There is many boilerplate code in your version.
For what is this for-loop?

I was a little bit playing a round in your code. Have a look at this:
