Suppose we have a binary string s, now let us consider an operation where we select a bit and flip its value from 0 to 1 or vice-versa. We have to find the minimum number of operations needed to get a string with no three identical consecutive bits.So, if the ... Read More

Suppose we want to develop a data structure that can build up with an expire time, and supports a function that takes user id and a timestamp. This will check whether a user with given user_id at time given timestamp the request fails or not. It will fail only when ... Read More

Suppose we want to develop a data structure that can build up with a list of integers, and there is a function to find sum of elements from index i to index j-1 whenever we require in an efficient way. There are two functions.Constructor that constructs a new instance with ... Read More

To return a new Timedelta floored to this resolution, use the timedelta.floor() method. For seconds floored resolution, set the freq parameter to the value S.At first, import the required libraries −import pandas as pdTimeDeltas is Python’s standard datetime library uses a different representation timedelta’s. Create a Timedelta objecttimedelta = pd.Timedelta('4 ... Read More

To return a new Timedelta floored to this resolution, use the timedelta.floor() method. For minutely floored resolution, set the freq parameter to the value T.At first, import the required libraries −import pandas as pdTimeDeltas is Python’s standard datetime library uses a different representation timedelta’s.
