To perform ceil operation on the DateTimeIndex with specified frequency, use the DateTimeIndex.ceil() method. For frequency, use the freq parameter.At first, import the required libraries −import pandas as pdCreate a DatetimeIndex with period 5 and frequency as S i.e. seconds. The timezone is Australia/Adelaide −datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5, tz='Australia/Adelaide', freq='40S')Display DateTimeIndex −print("DateTimeIndex...", datetimeindex) Ceil operation on DateTimeIndex date with specified frequency −print("Performing ceil operation...", datetimeindex.ceil(freq='us'))ExampleFollowing is the code −import pandas as pd # DatetimeIndex with period 5 and frequency as S i.e. seconds # timezone is Australia/Adelaide datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5, tz='Australia/Adelaide', freq='40S') # display DateTimeIndex ...

Suppose we have three values n, total, and k. Now consider a list of size n whose sum is same as total and where the absolute difference between any two consecutive elements is at most 1. We have to find the maximum value at index k of such a list.So, if the input is like n = 5 total = 15 k = 3, then the output will be 4, because one possible list is like [3, 2, 3, 4, 3], maximum element that is found at index 3 is 4.To solve this, we will follow these steps −x := ...

To perform ceil operation on the DateTimeIndex with microseconds frequency, use the DateTimeIndex.ceil() method. For microseconds frequency, use the freq parameter with value ‘us’.At first, import the required libraries −import pandas as pdCreate a DatetimeIndex with period 5 and frequency as S i.e. seconds −datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5, tz='Australia/Adelaide', freq='40S')Display DateTimeIndex −print("DateTimeIndex...", datetimeindex) Perform Ceil operation on DateTimeIndex date with microseconds frequency. For microseconds frequency, we have used 'us' −print("Performing ceil operation with microseconds frequency...", datetimeindex.ceil(freq='us'))ExampleFollowing is the code −import pandas as pd # DatetimeIndex with period 5 and frequency as S i.e. seconds # timezone is Australia/Adelaide ...

To perform ceil operation on the DateTimeIndex with milliseconds frequency, use the DateTimeIndex.ceil() method. For milliseconds frequency, use the freq parameter with value ‘ms’.At first, import the required libraries −import pandas as pdCreate a DatetimeIndex with period 5 and frequency as S i.e. seconds. The timezone is Australia/Adelaide −datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5, tz='Australia/Adelaide', freq='40S')Ceil operation on DateTimeIndex date with milliseconds frequency.

Suppose we have a list of numbers called nums, we also have another value k, we have to find the kth (starting from 0) smallest element in the list. We have to solve this problem in O(n) time on average.So, if the input is like nums = [6, 4, 9, 3, 1] k = 2, then the output will be 4, as after sorting the list will be like [1, 3, 4, 6, 9], the kth smallest element is 4.To solve this, we will follow these steps −maxHeap := a new empty heapfor i in range 0 to k, doinsert ...

Suppose we have a list of numbers called counts where counts[i] represents the number of items are of type i. We also have another value k. We have to find the maximum number of groups of size k we can find, such that each group must have items of distinct types.So, if the input is like counts = [2, 3, 5, 3] k = 2, then the output will be 6, because let four types of items are represented by a, b, c, d respectively. We can have the following groups of k = 2, where all elements are of ... Read More
