Password

Taro had his own personal computer and set a password for login. However, Taro inadvertently forgot the password. Then, remembering that there was a piece of paper with the password written down, Taro found the paper and was surprised to see it. The paper was cut and there were only fragments, and there were some stains that made it unreadable. Taro decided to guess the password by referring to the memo.
