1 + 11 + 1111+ 11111+ ..... + 11111(2016個)
結果是幾位數
用什么數據結構
有幾個6
寫算法
'''
a = [];
m = 0;
six = 0;
for i in range(2016,0,-1):b = (i+m) % 10;m = (i+m) / 10;    a.append(b)if b==6:six = six + 1;
if m>0:a.append(m)
print len(a) #2016
print six #226
print 'hello'
'''
c = reversed(a)
for i in list(c):print i,;
