Series36. An integer K and K sets of nonzero integers are given. Each set contains at least two elements, the sign of its completion is the number 0. Find the number of sets whose elements increase.

Solution in Python 3:

import random

K = random.randrange(1,7)

print("K = ",K)

count_inc = 0
for i in range(0,K):
    x_prev = random.randrange(1,4)
    print(x_prev,end="; ")
    x = random.randrange(1,4)
    print(x,end="; ")
    if x > x_prev:
        flag = True
    else:
        flag = False
    while True:
        x_prev = x
        x = random.randrange(0,4)
        print(x,end="; ")
        if x == 0:
            break
        if not (flag and x > x_prev):
            flag = False
    print()
    if flag:
        count_inc += 1
print("Number of increasing series: ",count_inc)
