HackerEarth ICPC Team Management problem solution

In this HackerEarth ICPC Team Management problem solution Little Chandan is an exceptional manager - apart from his role in HackerEarth - as the person who has to bug everyone, in general... and if possible, try to get some work done.

He's also offered a job as the coach of the best Russian teams participating in the ACM-ICPC World Finals. Now, Chandan is an extremely good coach, too. But he's a weird person who thrives on patterns in life, in general. So, he has decided that if there are n number of students in total, and he is supposed to divide them into camps of k students - he wants them to be arranged in such a way that the length of names of all the students in a camp is equal.

I know, totally weird, right?

for i in xrange(tc):
n, k = map(int, raw_input().split())
l = [0]*1000
ok = True
assert(n>0 and n<1001)
assert(k>0 and k<1001)
for j in xrange(n):
a = raw_input()
l[len(a)] +=1
for z in l:
if z%k!=0:
ok = False
if (ok):
print "Possible"
print "Not possible"
