One sweltering day, I was scooping ice cream into cones and told my four children they could "buy" a cone from me for a hug. Almost immediately, the kids lined up to make their purchases. The three youngest each gave me a quick hug, grabbed their cones and raced back outside. But when my teenage son at the end of the line finally got his turn to "buy" his ice cream, he gave me two hugs. "Keep the changes," he said with a smile.

输入样例以空格分割，未换行
一定注意换行要写在前面
要不就空格了
还有一定是else if 不是 if
if会导致每行开头多出来个空格
