yes it is greedy bro i also think ... simple maniplutaion with index

We can solve the first question using sliding window technique by take the window size = k and checking the ith and kth position for T and P. If ith and kth index is T and P, increment the count and move the window to right.

Yes...

[@SaurabhSharma420]

The first question was very simple, 2 iteration (forward and backward) would have done the task. The question would have been solved for not more than 20 mins.

[@nikunjkhakhkhar1030]

That seems to be a greedy approach which won’t work in second case since if P at index 2 catches T at index 1 then P at index 3 won’t be able to catch T at index 0 since distance is larger than k=2, so I don’t think it will work.

[@ShubhamKumar-pv8pj]

@@KeertiPurswani definitely it help ma'am for student like me who just get admission in college 😊

[@shivabansfore7510]

the approach for first program is very simple it is a greedy problem where you just need to catch the theif to your leftmost in range so that the distance between theif and police decreased and you can catch maximum thiefs.

[@darshanmukadam]

Or check left and right both?

[@pgigamingtelugu3505]

Used the concept of Stack to solve this. Like I used a police stack to store the indices of Police and another stack for theif. I used this because the condition states that each police can only catch one theif which indicates popping both the indices from each stack because they are of no use later. So the time complexity would be O(n) and Space complexity is O(n).

[@suryanshsinghchauhan5750]

An Optimized solution for the second question would be to use binary search. the range of possible answers would be [1 - max number in given array] . we can just apply the binary search on this range and for each mid which we encounter we will just check whether or not it is possible to get that mid as the max number. If it is possible to get the mid as max we will check in the left part of the array and store the mid as ans, and if it is not possible for us to get that mid as max in given array we will check in the right part. we will do it until low < high. If low >=high we will come out of the loop. I hope it does make sense 🙂🙂

[@timetoknow3171]

Hi , I came across the video after watching the striver mock interview . Worth it .

[@souravsinha4173]

I think Nishant bhaiya's approach for the second question will fail for the testcases like 2,100 and k = 1. Here Max(A) = 100 , Max2(B) = 2 ; So , C = 100 - 2 = 98 ; after inserting in priority queue we get {98 , 2 , 2} in priority queue. Since we have already exhausted our k(k was 1), our max answer will be 98 , but ideally it should have been 50.(If we had simply divided it by 2).

[@abhishekshrivastava9895]

second question approach will fail for tc [ 8 , 12 ] and k = 2 According to his approach answer will be [ 8 , 8 , 4] -> [ 4 , 4 , 8 , 4 ] so it is 8 whereas answer will be 6 [8 ,12] -> [ 8 , 6 , 6] -> [4,4,6,6]

Brute force will be O(n*k) for each policeman check from kth distance at left until there is thief. Optimal O(n) use queue for thieves.

[@nikcsm]

A very simple solution is For each policemen, tabulate every element at k distance from him thus their positions are already known as index_of_police + or - k . And then for each of them , try marking the left thief first and then if left DNE, then mark the right one. Once a T is marked, don't touch him again.

[@adi807980]

First Question with O(n*2) brute force approach inputarr=["T","T","T","P","P","T","T","P","P","P","P","T","T","T"] temparr= [0 for i in range(len(inputarr))] k=1 k=k+1 count=0 print(temparr) for i in range(len(inputarr)): if inputarr[i]=="P": for j in range(len(inputarr)): if (inputarr[j]=="T") and (abs(j-i)

[@ashutoshsingh5568]

Max thief count problem solution has been made a little complicated by Nishant as I solved it with simple nested for loops and one Boolean array which will set an index to true whenever a thief is caught and based upon that Boolean value of thief index I can move forward. Finally I can count the total true values and that is the total count of thieves caught.

Slide the window by 1, (reduce the count of the item removed from window , if any left and add new item) Keep doing this till window reaches end. Correct me if this solution won't work .

Hi Ankit, If you notice, he is doing the same thing finally. Instead of saving two vectors like he did, you are using hashmap And he used 2 iterators (2 pointers) and you are calling it window technique.
