【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
