It returns 5.0 instead of 4.5 when [4,5,5,4] goes in. You cannot take the int()s out because then it'll say you cannot use floats as indices of a list.

# 15/15: What is wrong with this code?

Let's see if we can reduce this to a simple algorithm:

```
def median(n):
n.sort()
j = len(n)/2.
k = int(j)
if j == k:
m = (n[k] + n[k-1])/2.
else:
m = n[k]
return m
print median([4,5,5,4]) # 4.5
```

It is another thing altogether to attempt to access the array elements by their median, since in even count arrays, the median is a float, and not necessarily a value in the array. We can use midpoint arithmetic to zero in on the two middle elements, which is easy enough to reason out.
