I got WA all the time for this problem. I guess I have overlooked something unsure, since my program passed the test cases given in the problem description. Could someone post some critical inputs? Thanks.

I think no critical input is required


Here my algorithm is :

after liquidate all debentures
from creditor to debtor

now check that
any of those banks monetary reserves is <0
if yes
print "N\n"
else
print "S\n"

thats
