【笔试题目】小米2020秋招测试开发

题目一：

import sys
try:
while True:
line = sys.stdin.readline().strip()
if line == '':
break
sum=0

for i in range(1,101):
sum+=i
if sum == int(line) and int(line)!=5050:
print i
break

if sum==5050 and int(line)==5050: #注意刚好等于5050的情况
print 100
elif sum==5050:
print 'No'
# lines = line.split()
# print int(lines[0]) + int(lines[1])
except:
pass

测试用例通过100%

题目二：

input_1=raw_input('')
input_2=raw_input('')

list2=[]

for j in input_2:
list2.append(j)

str=''
for i in input_1:
if i not in list2:
str+=i

print str

测试用例通过67%，暂时不知道问题出在哪里
