Our hero Ninja is organizing a coding competition where only two teams can participate simultaneously. To make the competition interesting and fair, both the teams should have an equal number of members. As an organizer, Ninja got the task of making the two teams.

There are some conditions for creating teams. For each competition, he will be given a number ‘N’, and for each divisor ‘D’ of ‘N’ ( including 1 and ‘N’ itself ), he will add a member:

1) to the first team if ‘D’ is even.

2) to the second team if ‘D’ is odd.

Since Ninja is very busy organizing the event, he wants you to help him with the task. Your task is to tell Ninja if he can create two teams with an equal number of members.

For Example:

For ‘N’ = 10,
The divisors are:
1, 2, 5, 10.
The first team will have two members corresponding to divisors 2 and 10.
The second team will have two members corresponding to divisors 1 and 5.
So, in this case, Ninja can make two teams.

Bob has just turned 18 years old and has opened a Bank account. However, since he has just opened his bank account he is not very experienced about the working of banks, therefore he asks for your help. Bob wants to know whether the IFSC Code given by the bank is valid or not, can you help him?

A valid IFSC (Indian Financial System) Code must be of the following format:-

1) The string should be 11 characters long.

2) The first four characters of the IFSC Code should be upper case alphabets.

3) The fifth character should be 0.

4) The last six characters should be alphanumeric.
