Answer the question in Python, thank you.

Vyasa has to complete a programming assignment overnight. He has to write n lines of code before morning. He is dead tired and he tries drinking some black coffee to keep him awake. But each time he drinks a cup of coffee he stays awake for a short amount of time but his productivity goes down by a constant factor k This is how he plans to write the program. He will write the first v lines of code, then drink his first cup of coffee. Since his productivity has gone down by a factor of k he will write v // k lines of code. He will have another cup of coffee and then write v // k**2 lines of code. He will have another cup of coffee and write v // k**3 lines of code and so on. He will collapse and fall asleep when v // k ** p becomes 0. Now Vyasa does want to complete his assignment and maximize on his sleep. So he wants to figure out the minimum allowable value of v for a given productivity factor that will allow him to write at least n lines of code before he falls asleep.

Input

2 300 2 59 9 The first line is T the number of test cases. This will be followed by T lines of input. Each line of input will have two numbers nand k. nis the number of lines of code to write and kis the productivity factor, where 1 n106and 2 k10

Output

Do not worry if your times do not match ours exactly. They are given just for comparison purposes. For this assignment, main has been written completely for you, and nothing needs to be changed in it. You will be solving this problem in 2 ways. First, you will write a function that uses a linear search to solve the problem. Then you will write a function that uses a modified binary search algorithm to solve it again. Both functions will return the same answer, but the binary search method will usually be faster. It is recommended that you write a helper function, which given a value v representing the number of lines Vyasa writes before his first cup of coffee and a value k, the productivity factor, will calculate the number of lines Vyasa will write before falling asleep. This can be called in both the linear and binary functions to make the computations easier.

Starter Code

import sys

import time

# Input: v an integer representing the minimum lines of code and

# k an integer representing the productivity factor

# Output: computes the sum of the series (v + v // k + v // k**2 + ...)

# returns the sum of the series

def sum_series (v, k):

# Input: n an integer representing the total number of lines of code

# k an integer representing the productivity factor

# Output: returns v the minimum lines of code to write using linear search

def linear_search (n, k):

# Input: n an integer representing the total number of lines of code

# k an integer representing the productivity factor

# Output: returns v the minimum lines of code to write using binary search

def binary_search (n, k):

def main():

# read number of cases

line = sys.stdin.readline()

line = line.strip()

num_cases = int (line)

for i in range (num_cases):

line = sys.stdin.readline()

line = line.strip()

inp = line.split()

n = int(inp[0])

k = int(inp[1])

start = time.time()

print("Binary Search: " + str(binary_search(n, k)))

finish = time.time()

print("Time: " + str(finish - start))

print()

print("Linear Search: " + str(linear_search(n, k)))

finish = time.time()
