from itertools import combinations
n = int(input())
l = [int(i) for i in input().split()]
a5, b3, rest = [],[],[]
for i in l:
if i%5 == 0:
a5.append(i)
elif i%3 == 0:
b3.append(i)
else:
rest.append(i)
valid = False
if rest == [] and sum(a5) == sum(b3):
valid = True
for i in range(len(rest)):
for c in combinations(rest,i):
if sum(a5) + sum(c) == sum(l) - sum(a5) - sum(c):
valid = True
break
print('true' if valid else 'false')
感觉用combinations像是在偷懒，看个乐吧
