Java program asked to execute  

Aditya Verma: Find the length of the longest substring without repeating characters.

Sample 1:
Input – String a = “xdfrxabc”
Output – 4 

Reasoning – “xdfr” is the substring before x repeats

Sample 2:
Input – String b = “aaaaa”
Output – 1

Reasoning – “a” is substring before repeatation

Sample 3:
Input – String c = “qcvvopit”
Output – 4

Reasoning – “opit” is the substring. qcopit is a sub sequence and not a substring.
