Suppose we have two values n and m. We have to find number of possible arrangements of humble matrices of order n x m. A matrix is said to be humble whenIt contains each element in range 1 to n x m exactly oncefor any two indices pairs (i1, j1) and (i2, j2), if (i1 + j1) < (i2 + j2), then Mat[i1, j1] < Mat[i2, j2] should hold.If the answer is too large then return result mod 10^9 + 7.So, if the input is like n = 2 m = 2, then the output will be 2, because there ...

Suppose, there is n number of cities and m roads connecting the cities. The citizens of the people need markets where they can buy their commodities. Now, there are no markets in the cities, and the roads between the cities are under construction.A two-way road can be built between two cities if (i) The city contains a market; (ii) The cities can be visited by the road where there is a market. The cost of building a road is x, and building a market is y and they are given. We have to find out the minimal cost to provide ... Read More

Suppose, we have a tree that has all of its nodes numbered as 1 to n. Each of the nodes contains an integer value. Now if we remove an edge from the tree, the difference in the sum of the node values of the two sub-trees has to be minimal. We have to find out and return the minimum difference between such sub-trees. The tree is given to us as a collection of edges, and the values of the nodes are also provided.So, if the input is like n = 6, edge_list = [[1, 2], [1, 3], [2, 4], [3, ... Read More

To check if the given timestamp is on offset or not, use the CustomBusinessHour.is_on_offset() in Pandas. Pass the timestamp as an argument to check.At first, import the required libraries −import pandas as pdSet the timestamp object in Pandas −timestamp = pd.Timestamp('2021-11-14 05:20:30') Create the CustomBusinessHour Offset. CustomBusinessHour is the DateOffset subclass −cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:30")Add the offset to the Timestamp and display the Updated Timestampprint("Updated Timestamp...", timestamp + cbhOffset) Check if the given timestamp is on offset or not −offset = cbhOffset.is_on_offset(pd.Timestamp('2021-11-20 05:20:30'))Display the result −print("Check if the given timestamp is on offset or not...", offset) ExampleFollowing is ...
