Series31. Integers K, N and K sets of integers with N elements in each set are given. Find the number of sets containing the number 2. If there are no such sets, output 0.

Solution in Python 3:

import random

N = random.randrange(1,7)
K = random.randrange(1,7)

print("N = ",N)
print("K = ",K)
S = 0
for i in range(0,K):
    flag = False
    for j in range(0,N):
        x = random.randrange(0,4)
        print(x,end="; ")
        if x == 2:
            flag = True
    if flag:
        S += 1
    print()

print()
print("Количество наборов, содержащих 2:",S)
