Thanks for the test case. I got the correct output. I don't know why I keep getting WA.

Has anyone got an interesting set of test data I can run through my program? It works for the ones I come up with, but I keep getting WA.

Here's one set I tried:
6
a 3
b 4
c 15
d 20
e 21
f 24
14
a 3
b 6
c 8
d 9
e 15
f 16
g 17
h 70
i 77
j 83
k 88
l 100
m 107
n 120
0

Output:
c
f

g
n

Thanks ...
