from tcgen import *
# Bounds are 1..1e5 by default
N = Integer(2, 100000)
print(N)
print(Array(N, Integer(10000)))

from tcgen import *
class Gen(Generator):
    def generate(self, case_num):
        N = Integer(L=2, wcnt=20)  # Weighted random
        K = Integer(100)
        self.p(N, K)
        self.p(Array(N, U=10000))

gen = Gen()
print(gen.get_test_cases(10))
print(gen.get_test_case())

from tcgen import *
A, B = Integer(), Integer()
print(A, B)
# 1 <= N <= A+B
N = Integer(A + B)
print(N)

from tcgen import *
N = Integer()
print(N)
M = Integer(2 * N)
print(M)
print(Graph(N, M).shuffle())

from tcgen import *
N = Integer()
print(N)
print(StrictlyIncreasing(N).shuffle())
