1005 Number Sequence
1005.py输出与昨天的2035.py出现一样的问题，后续一并解决

1002A+B Problem II

#encoding:utf8
#1002 A+B Problem II
#最后一个结束不应该还有空格，还没想通该怎么写

n=int(raw_input())
l=[]
for i in range(n):
    l.append(raw_input().split(' '))
    l[i]=map(int,l[i])

for i in range(n):
    print 'Case',i
    print l[i][0] ,'+',l[i][1],'=',sum(l[i])
    print ''

1003Max Sum
1002.py和1003.py最后一个输出后不应该还有空格，还不知道怎么解决

#encoding:utf8
#1003 Max Sum

t=int(raw_input())

lst=[]
for i in range(t):
    s.append(raw_input().split(' '))
    s[i]=map(int,s[i])
# print s
for l in s:
    maxnum=l[0]
    for i in range(1,len(l)):
        for j in range(1,len(l)):
            # m=sum(l[i:j+1])
            #print m
            if maxnum<=sum(l[i:j+1]) and i!=j:
