Most engineers make critical mistakes on their resumes -- we can fix your resume with our custom resume review service. And, we use fellow engineers as our resume reviewers, so you can be sure that we "get" what you're saying.
Our Mock Interviews will be conducted "in character" just like a real interview, and can focus on whatever topics you want. All our interviewers have worked for Microsoft, Google or Amazon, you know you'll get a true-to-life experience.
Hey guys, I think it would be simplest just to use a HASHSET.
With the if statement we try to add the current character to the hash set; if we succeed, it means that the char is encountered for the first time, so we increment the counter i, otherwise (when if returns false), we just remove the particular char. Note that the value of i is not incremented.
Hope it helps. :)
