Clinic #06 - Longest Substring Without Repeating Characters

Pattern: Sliding Window · LC 3

Yeh board ek string ke upar do pointer dikhata hai jo aage khiskte hain, jaise ek chhoti khidki jo repeat milte hi thoda simat jaati hai - par kabhi peeche nahi jaati.

Before you start. Tumhe itna pata hona chahiye ki ek string letters ki ek line hoti hai, aur har letter ka apna index (position number, jaise ghar ka number) hota hai. Pichhle clinic, Clinic #05 - Two Sum, mein tumne dekha tha ki ek hash map “maine yeh pehle dekha hai kya?” turant bata deta hai - wahi cheez yahan bhi kaam aayegi.
