CodeRankGPT -
An AI Assistant for your coding test. Make sure to get hired 🎯
This Python program is designed to solve a problem where the user is given multiple arrays of integers and a number 'm'. The task is to find the maximum possible sum of the squares of numbers, each picked from different arrays, modulo m. The number of arrays and the value of 'm' are provided by the user at runtime.

The solution uses the itertools.product function to generate all possible combinations of numbers, each picked from different arrays. For each combination, it calculates the sum of the squares of the numbers and takes the modulo m of the result. It keeps track of the maximum such value encountered so far. The approach is exhaustive and ensures that the maximum possible value is found.
import itertools
k, m = map(int, input().split())
main_ar = []
for _ in range(k):
ar = list(map(int, input().split()))
main_ar.append(ar[1:])
all_combination = itertools.product(*main_ar)
result = 0
for single_combination in all_combination:
result = max(sum(x * x for x in single_combination) % m, result)
print(result)
