To prepare for ACM contest, the judge
sometimes has to generate random passwords for the users. The problem is that
there are always some confusing passwords since it is hard to distinguish 1
(one) from l (L in lowercase), or 0 (zero) from O (o in uppercase). One
solution is to replace 1 (one) by @, 0 (zero) by %, l by L, and O by o. Now it
is your job to write a program to check the accounts generated by the judge,
and to help the juge modify the confusing passwords.
Each input file contains one test case.
Each case contains a positive integer N (<= 1000), followed by N lines of
accounts. Each account consists of a user name and a password, both are strings
of no more than 10 characters with no space.
For each test case, first print the number
M of accounts that have been modified, then print in the following M lines the
modified accounts info, that is, the user names and the corresponding modified
passwords. The accounts must be printed in the same order as they are read in.
If no account is modified, print in one line "There are N accounts and no
account is modified" where N is the total number of accounts. However, if
N is one, you must print "There is 1 account and no account is modified"
instead.
