【一眼秒杀】三道蓝桥杯真题（六）

一、费里的语言

N = int(input())
LIST = []
for i in range(N):
    LIST.append(input())

for i in LIST:
    s = i
    LIST.remove(i)
    if s in LIST:
        print(s)
        sys.exit()
print("NO")

二、找零问题

n=eval(input())
l=[100,50,20,5,1]
for i in l:
  c=0
  while n-i>=0:
    n=n-i
    c=c+1
  print('{}:{}'.format(i,c))

三、倍数个数

a = 0
for i in range(10000,90000):
        if i % 128 == 0:
                a = a + 1
print(a)
