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

之前面了一家外包的大模型，基本上都能答出来，那面试官感觉还没我懂，然后把我挂了，我都还没嫌弃他是外包，他把我挂了……
