=> By Basic Counting Principle, there are 26 alphabets for first slot, 26 for second, and hence, forward.
=> Total number of 10 character password = Number of ways in which a 10 - lettered word can be made out from the 26 alphabets
=> Total number of 10 character = 26 x 26 x 26 x ... x 26 ( 10 times )
= 26¹⁰
