We are given an integer array and the task is to firstly fetch the prefix of an array and then multiply it with -1, secondly calculate the prefix sum of an array and lastly find the maximum sum from the prefix array generated.Prefix array is generated as −First element of prefixArray[0] = first element of an arraySecond element of prefixArray[1] = prefixArray[0] + arr[1]Third element of prefixArray[2] = prefixArray[1] + arr[2]Fourth element of prefixArray[3] = prefixArray[2] + arr[3] …..etc.Let us see various input output scenarios for this -In − int arr[] = {2, 4, 1, 5, 2}Out − Prefix array is: ...

To check whether the CustomBusinessDay Offset has been normalized or not, use the CustomBusinessDay.normalize property in Pandas.At first, import the required libraries −import pandas as pdSet the timestamp object in Pandas −timestamp = pd.Timestamp('2021-10-22 03:10:35') Create the CustomBusinessDay Offset. CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays. Weekmask of valid business days. We have normalized the CustomBusinessDay using the "normalize" parameter −cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri', normalize=True)Add the offset to the Timestamp and display the Updated Timestamp −print("Updated Timestamp...", timestamp + cbdOffset) Check whether the CustomBusinessDay Offset is normalized or not ...

To return the name of the frequency applied on the given CustomBusinessDay offset object, use the CustomBusinessDay.name property.At first, import the required libraries −import pandas as pdSet the timestamp object in Pandas −timestamp = pd.Timestamp('2021-12-31 08:35:10') Create the CustomBusinessDay Offset. CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays −cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri')Add the offset to the Timestamp and display the Updated Timestamp −print("Updated Timestamp...", timestamp + cbdOffset) Return the name of the frequency applied on the given CustomBusinessDay object −print("The name of the frequency on the CustomBusinessDay object..", cbdOffset.name)ExampleFollowing is ...

A polite number is a positive number that can be written as the sum of 2 or more consecutive positive numbers.The series of polite numbers are3 5 6 7 9 10 11 12 13 14...There exists a formula to find the n-th polite number. The formula is n + log2(n + log2(n)). The default log computes with base e. We need to compute using base 2. Divide the default log result with log(2) to get the value of log with base e.AlgorithmAlgorithm to the n-th polite number is straightforward.Initialise the number N.Use the above formula to compute the n-th polite ...

We are given a 2-D array of integer elements forming the matrix. The task is to calculate the count of minimum sum by pulling the submatrix from the matrix so formed.Let us see various input output scenarios for this -In −int matrix[size][size] = { {2, 3, -1, 5}, {-2, 9, -1, 6}, { 5, 6, 9, -9}, { -6, 1, 1, 1} }Out −Minimum sum submatrix in a given 2D array is: -9Explanation −we are given a 2-D array of size 4x4 i.e. 4 rows and 4 columns. Now, we will find out the sub-matrix from the given matrix such ... Read More
The numbers formed with the digits {0, 1, 2, 3, 4, 5} are0, 1, 2, 3, 4, 5, 10, 11, 12, 13, 14, 15, 20, 21, 22, 23, 24, 25, etc.., We can form the above sequence using the first 6 digits. Let's see an example of the formation of numbers. 1 * 10 + 0 = 10 1 * 10 + 1 = 11 1 * 10 + 2 = 12 1 * 10 + 3 = 13 1 * 10 + 4 = 14 1 * 10 + 5 = 15Similarly, apply for the number 2, 3, 4, ... Read More
