Bro it took me 2 years to start your course. The entire playlist has been saved since you uploaded all the 60+ videos as a playlist. But since last 2 weeks I have been watching them relentlessly and the amount of confidence I have gained in my coding skills has drastically improved. Big thanks to you my man. And I really crack up when you crack a joke in between the lecture. May God Bless you Kunal just like you have blessed us all. I am a QA Engineer btw

How Kunal make course- "complete dsa course" How Ed tech mafia make courses - Dsa for beginners Dsa intermediate level Dsa advance level Dsa for FAANG Dsa with c++ Dsa with Java Dsa with python Dsa in real life . Dsa in 100 days. Inshort it's their business to keep making courses otherwise what they will do if they make a single course. Hope u r getting their strategy for non ending course making business.

[@jaynimje3790]

Help. I have doubt. Unless we tell a function what to return, it wont return anything. Then how does the Binary search know that it has to return the index of target. I am posting this on random comments. If anyone knows the answer to this please comment.

[@shivendrashrivastwa4566]

@@jaynimje3790 Brother, he is returning the mid and mid is that index. 😊

[@ousmanesangary658]

@@jaynimje3790 Our goal is to find and return the middle element only. The start and end pointers are just there to go left or right whenever the target element is less or greater than the middle element. If the target element isn't found, we will then return -1 instead of the index of the middle element. Hope this helps.

[@Krishnaeagle-ex4zj]

Instead of remembering mid = start +(end-start)/2 can't we do the same as mid = (start/2) + (end/2) ??
