牛客竞赛OJ在线编程常见输入输出练习场题解（Python版）

问题：
牛客网的题需要自己写输入输出，最好提前熟悉下。这一场的竞赛时间是10分钟，11道题。我第一次做是没能在10分钟内做完。

注意：注意变量类型，input的是字符，需要int。注意数组下标范围。
题A：

import sys
for line in sys.stdin:
    a = line.split()
    print(int(a[0])+int(a[1]))

题B：

lines=int(input()) 
for n in range(1,lines+1):
    list=[]
    list.extend([int(i) for i in input().split()])
    c = list[0]+list[1]
    print(int(c))

题C：

import sys
for line in sys.stdin:
    a = line.split()
    if int(a[0]) == 0 and int(a[1]) == 0:
        break
    else:        
        print(int(a[0])+int(a[1]))

题D：

import sys
for line in sys.stdin:
    a = line.split()
    if int(a[0])==0:
        break
    else:
        c = sum(int(a[i])for i in range(1,int(a[0])+1))
        print(c)

题E：

import sys
lines = int(input())
for n in range(1,lines+1):
    a = input().split()
    c = sum(int(a[i]) for i in range(1,int(a[0])+1))
    print(c)

题F：

import sys 
for line in sys.stdin:
    a = line.split()
    c = sum(int(a[i]) for i in range(1,int(a[0])+1))
    print(c)

题G：

import sys
for line in sys.stdin:
    a = line.split()
    c = sum(int(a[i]) for i in range(len(a)))
    print(c)

题H：

import sys
lines = int(input())
for line in sys.stdin:
    a = line.split()
    a.sort()
    c = ' ' .join(a)
    print(c)

题I：

import sys
for line in sys.stdin:
    a = line.split()
    a.sort()
    c = ' '.join(a)
    print(c)

题J：

import sys 
for line in sys.stdin:
    a = line.split()
    a = a[0].split(',')
    a.sort()
    c = ','.join(a)
    print(c)

题K：

import sys 
for line in sys.stdin:
    a = line.split()
    c = int(a[0])+int(a[1])
    print(c)

以上。
