Level up your coding skills and quickly land a job. This is the best place to expand your knowledge and get prepared for your next
interview.

Interesting Points -

* We don’t need to store the prefix sum array, if we pre-compute the number of 1s
* Precomputing the number of 1s takes an extra pass, but does not change the O(n) complexity
* The end case of iterating to ==length is needed to cover the possibility of flipping the rightmost 1, but remember to break as
the location is out of original string array.

class Solution {
public int minFlipsMonoIncr(String s) {

char sa = s.toCharArray();
int sum = 0, cnt1 = 0;
int min_flip = s.length();

S3 Design ( zoo kepeer, consistent hashing, range hashing)

1. We discussed about developing the storage layer
2. Coming up with simple interfaces and building more complex architectures over them
3. Understand how to use zookeeper and what use cases it is designed for.
