What is the logic behind string comparisons, why ("H">"c") is False and ("H">"C") is True? How does the case sensitivity works?

Answer 1

It checks for ASCII values.Google it.

Answer 2

Capital letter have ASCII values from 65-90, and small alphabets have values from 97-122.

Then H=72
C=68
c=99

Therefore 'H'>'c' is false but 'H'>'c' is true.

Hope this helps.
