### 有参考大佬的解法
s = input()  # xcopy /s c:\\ d:\\e # xcopy /s "C:\\program files" "d:\"
ls = []
if '"' not in s:
    for i in s.split():
        ls.append(i)
else:
    ss = s.split('"')
    for i in range(len(ss)):
        if i%2 == 1: # 引号里面分割出来位置总是奇数
            ls.append(ss[i])
        else:
            ls += ss[i].split()
print(len(ls))
for k in ls:
    print(k)
