Holy shit. I am a senior student of Computer Science and I never REALLY understood these concepts until I watched these videos. I am literally watching the entire playlist to understand Analysis of Algorithms better. You are amazing for taking the time to make these videos. Sending thanks all the way from Texas!

you are a senior cs student and you can't understand binary search ? wow, what do they teach you in that school ?

Abdul Bari is of the most gifted instructors I have ever seen on online videos. Thank you very much for the level of detail and the clarity of your explanations. I can say that your videos are the solid foundation for literally anyone studying these subjects before watching anything else. Congratulations!

Note that in practice doing mid = (L+H)/2 is not a good idea because it can cause an overflow since (L+H) can be greater than the list size. Instead, we should do mid = L+(H-L)/2 to avoid any possible overflow.

[@thean1585]

Damn I was stuck on this in python for a while, took your advice and it works, you sir are a legend!

[@rishav179]

we can do the floor division to avoid overflow.

[@davidomar742]

if you start l at 0 and h at length of list -1 you won't overflow

Sir,Array's counting starts from 0 to (n-1) but you have started the counting from 1?Is it possible to do that?

In your code, you return 0 if index is not found, but instead you should return False; returning 0 index will mean that element is found as the first item on array Here is python code for the same that you explained : def binarySearch(A,key): n = len(A) low = 0 high = n while (low

If we also check low and high index for key along with mid [(just like we check if arr[mid]==key)], we will do less iteration and time complexity will be improved too..... if(arr[low]==key || arr[high]==key || arr[mid]==key) --> return/low/mid/high;

thanks Abdul, I think the binary function should return -1 not '0'. '0' is still a valid index.

he is not returning index of array, but position ! so he is right!
