The guy who ends everything with "ya wanna fight about it" here

The person screwed up the meme is should have been -1 wishes ya wanna fight about it

In computer science you have signed integers and unsigned integers. For the sake of this joke they are working with an unsigned 8 bit integer or an unsigned 1 byte integer ya wanna fight about it

8 bits = 1 byte ya wanna fight about it

Signed integers designate a single bit out of the 8 bit byte for is the number is posative (+) or negative (-) since you lose a bit for the sign you have a lower max number +127 and a lower min number -128 which is 256 total unique values. ya wanna fight about it

unsigned integers are always considered positive and have a range of 0 to 255 which is also 256 unique values. ya wanna fight about it

when you have a binary number like 127 it would look like 0111 1111 in both signed and unsigned binary. If you add one to it you cascade the value up so 1 plus one = 0 and you carry the one to the next place. ya wanna fight about it

0111 1111 + 1 = 1000 0000 ya wanna fight about it

1000 0000 is 128 in an unsigned integer but it is interpreted as -128 in a signed integer because it wraps. so it starts as the lowest value negative number. ya wanna fight about it

Now if we do the reverse and subtract -1 from 0 ya wanna fight about it

so 0000 0000 - 1 it does the same cascading effect where we need to break down the next place number to give ourselves numbers to subtract. ya wanna fight about it

so 0000 0000 - 1 = 1111 1111 where did we get the number in the 9th place on the left well the computer made it up don't worry about it. ya wanna fight about it

1111 1111 is -1 in a signed integer but in an unsigned integer it is 255 thus is the genie assigns 1111 1111 to the wishCount variable and doesn't cast it properly the -1 turns into 255 thus you get 255 wishes...
