Will You?

Once Mary heard a famous song, and a line from it stuck in her head. That line was "Will you still love me when I'm no longer young and beautiful?". Mary believes that a person is loved if and only if he/she is both young and beautiful, but this is quite a depressing thought, so she wants to put her belief to the test.

Knowing whether a person is young, beautiful and loved, find out if they contradict Mary's belief.

A person contradicts Mary's belief if one of the following statements is true:

• they are young and beautiful but not loved;
• they are loved but not young or not beautiful.

Example

• For young = true, beautiful = true, and loved = true, the output should be

  will_you(young, beautiful, loved) = false

  Young and beautiful people are loved according to Mary's belief.

• For young = true, beautiful = false, and loved = true, the output should be

  will_you(young, beautiful, loved) = true

  Mary doesn't believe that not beautiful people can be loved.

Input/Output

• [input] boolean young

• [input] boolean beautiful

• [input] boolean loved
