Answers
Using the knowledge in computational language in python it is possible to write a code that you are given a data.csv file in the /root/customers/ directory containing information about your customers.
Writting the code:import pandas as pd
# you can replace the path to csv file here as "/root/customers/data.csv"
df = pd.read_csv("data.csv")
print(df,"\n")
country = df.groupby('COUNTRY')['CONTRCNT'].sum()
country = country[country==country.max()]
print(country,"\n")
# Once groupby is used, the particular columns becomes index, so it can be accessed using below statement
print(country.index.values, "\n")
# Index is used as -1 in case there are multiple data with same value, and data is sorted and we will be needing last data value only
print("Country with the largest number of customers' contracts:", country.index.values[-1], "({} contracts)".format(country[-1]))

Answers
A recursive function is a piece of code that executes by referencing itself. Simple or complex recursive functions are both possible.
What Does Recursive Function Mean?A recursive function is a programming construct that executes by referencing itself. Recursive procedures can be straightforward or complex. They provide more effective code development, for example, when listing or assembling collections of integers, texts, or other variables using a single repeated procedure.In programming, recursive operations frequently rely on the construction of loops, where the initial variable is called repeatedly while being changed by the loop. The factorial function is a straightforward illustration of a recursive function because it multiplies a number by itself while lowering it sequentially. Recursive functions can relate to a variety of additional self-referential looping functions, such as those where n = n + 1 is given an operational range.Programmers and others have created far more complex functions that also use the recursion concepts in addition to the more straightforward recursive functions.
