I'm working on a programming algorithm and need a little math help. I'm in 10th grade and I think the question I'm asking is actually a permutation and combination logic question. Okay, so I've 62 characters as follows:
I want to know how many unique characters can be made from this? For example, for length 1 character, there could be 62 unique characters. Length 2 character, there could be 00,01,02,03....AA,AB,AC...FA,FB,FC,FD...ZA,ZB,ZC...0A,0B,0C...,etc.
I hope you are getting me what I'm trying to say. And the maximum length of the string should be 7 characters.
So, in total, how many unique random strings can be generated from these 62 characters!?
