No wonder how demotivated I was when I saw that question and was looking for a good explanation since last 7 days (no, not even exaggerating). But, this man is love!!! Keep going @Striver :) You're our hope!!

[@yash-seth]

God tier explanation. I truly can't put in words how easily and clearly you were able to explain a seemingly confusing question!

I was struggling with Binary search on sorted array for a long time,
Your key point "Eliminate one half" has cleared my confusion.
Thank you so much Striver

[@reyanshmishra7676]

The best explanation I have found for this problem.
Alog is very simple now
1. Identity the sorted half.
2. Check if the target lies in the sorted half.
Thats it you need to do this two things only.

[@junaidahmed3615]

what an absolutely great explanation. i watched another video before this and it was so convoluted for no reason. yours is so simple and easy to grasp

[@junaiid0104]

crazy concept striver ! I'm just loving your binary search playlist!!!

[@beingproductive22]

here after love babar lec - 14 for rotated sorted array he is using the concept of pivot element which is little messy
but striver what a lovely lovely explanation
in 1 go i understood and coded it myself

[@Josuke217]

I learned recursion stack and queues from him , he's not a good teacher .

[@venkatsaireddy1412]

Thank You Raj Vikramaditya.
I am a scaler student , i fond of Your teaching skills more than scaler instructors.

[@ML-ok9nf]

One of the best explanations for this problem on the internet!

[@unknown2003august]

Notes for me☺
As we get our mid at any index checks arr[num]==target if it satisfies return here.
After that
Case 1>
Array is left sorted(we check it by standing on mid),
==>Checks where our target lies in sorted(between low to mid ) or outside it by using
if(arr[low]=target)
if it lies inside this it indicates we need to collapse window by taking high to mid -1 otherwise low to mid+1
Case 2>
Array is right sorted similarly we check for it and updates our low and high accordingly
if we never get it we return -1 to it

[@pratikkumarsingh8114]

Understood bhaiya , thw way of teching is another level, I don't have words to express my feelings. Thanks a lot, bhaiya!!!

[@mdsalimtauheedm-5810]

honestly I was very confused and demotivated after watching Rohit negi sir's explanation in paid course , i spent 2 hour to understand this problem but could not get it , after watching strivers explanation i get it only after single iteration. thanks a lot . now i am going to follow strivers AtoZ DSA

[@venkatesasrikanthdhulipala9486]

one small correction in the code it will fail if the array is [3,1] and target = 1
because of code in line no 9 i.e k

[@abhimanyuambastha2595]

Looked at neetcode video, then yours. His explanation was a bit confusing and had to do some examples to understand it. Yours almost made it a regular easy binary search

Yes , same code will be there for left rotared.
