Help Mr. Sidhu, your favourite math teacher, find the median mark on a class test. The first line will consist of , the number of marks. This line will be followed by lines with each containing an integer mark . Round to the nearest integer if necessary. We use standard mathematical conventions for rounding.
Sample Input 1
2 50 100
Sample Output 1
Sample Input 2
3 40 99 100
Sample Output 2
For anyone else wondering, "standard mathematical conventions for rounding" seems to mean round half up, instead of round half to even, which would have been my first guess.
why is my code WA 11x. My code works on the 2 Samples?????????? edit: the latest one
Try these two test cases:
The output should be something you can figure out yourself.
use math.ceil(), instead of round in python2/3 could be a useful hint
I tested my code out with the sample on an online compiler and it worked, but it doesn't seem to on here. Can someone take a look?
You have to sort the array in order to find the median.
Your code fails this case: 4 30 59 76 23
I'm failing test cases #7, #10 and #100. Can anyone please give me a hint?
You're not rounding.
And what's Testcase #100?
I would be interested to know why I am failing the last two test cases. Any hints?
Try reading the docs for
Is there anything I should watch out for in this problem?
and don't assume that the input is sorted. In your case, divide by 2.0 rather than by 2, or else the answer would be cast into an integer (rounded down for positive numbers; 1.9 => 1 instead of 2).
Thank you for your help!
Just round properly.
