Hi!
I am new into coding competitions and have started trying to solve past
problems. I got no problem while solving 2019 Qualification Round problems
A, B and C, but when it comes to the problem D, even when it works when I
run it locally, google sends me a Runtime Error (RE), but I don't really
know why this happens and I would really appreciate if someone could help
me.
I think the problem comes with the interactive part of the problem. Also I
want to notice that I know my solutions does not work for Test Set 2 since
I have not come with an answer for that, but for Test Set 1 it should work
fine, but as I said before I get an RE.
Here is the code I use to trying solving it in Python 3:
-------------------------------------------
def solve1(n):
l = len(bin(n).lstrip('0b'))
inp = [''] * l
for i in range(n):
a = bin(i).lstrip('0b').zfill(n)
for j in range(l):
inp[j] += a[n-j-1]
return inp , l
def solve2(m,l):
a = [''] * len(m[0])
p = []
for i in range(len(m[0])):
for j in range(l):
a[i] += m[l-j-1][i]
for k in a:
p.append(int(k,2))
return p
def get_values(n,a,b):
sol = []
for i in range(n):
if i not in a:
sol.append(i)
b -= 1
if b == 0:
break
return sol
def solve():
m = []
n, b, f = map(int, input().split())
inp , l = solve1(n)
for i in range(l):
print(inp[i] , flush = True)
m.append(str(input()))
p = solve2(m,l)
sol = get_values(n,p,b)
print(*sol , flush = True)
verdict = int(input())
t = int(input())
for _ in range(t):
solve()
----------------------------------------------
If someone knows why locally works with F = 10, but when I submit it to
Google I get the RE error I would be really happy.
Thanks in advance.
