/*

Encryption is a technique of coding messages to maintain their secrecy.

A String array of size 'n' where 'n' is greater than 1 and less than 10,

stores single sentences (each sentence ends with a full stop) in each row of the array.

Write a program to accept the size of the array.

Display an appropriate message if the size is not satisfying the given condition.

Define a string array of the inputted size and fill it with sentences row-wise.

Change the sentence of the odd rows with an encryption of two characters ahead of the original character. Also change the sentence of the even rows by storing the sentence in reverse order.

Display the encrypted sentences as per the sample data given below.

Test your program on the sample data and some random data.

Input: n=4

IT IS CLOUDY. IT MAY RAIN. THE WEATHER IS FINE. IT IS COOL.

Output: KV KU ENQWFA. RAIN MAY IT. VJG YGCVJGT KU HKPG. COOL IS IT.

Input: n=13

Output: INVALID ENTRY

/*Design a program which accepts your date of birth in dd mm yyyy format. Check whether the date entered is valid or not.

If it is valid, display "VALID DATE", also compute and display the day number of the year for the date of birth.

If it is invalid, display "INVALID DATE" and then terminate the program.

Testing of the program

Input: Enter your date of birth in dd mm yyyy format 05 01 2010

Output: VALID DATE 5

Input: Enter your date of birth in dd mm yyyy format 03 04 2010

Output: VALID DATE 93

Input: Enter your date of birth in dd mm yyyy format 34 06 2010

Output: INVALID DATE */
