Finding Reppoh Ecarg too difficult a game, the children of Ada Land prefer to play the game of Ecalevol. This game is a lot simpler: a player draws cards, and then exclaims `Ecalevol!`

if they win, or `I lost.`

if they lose.

All cards have an integer on them. A hand is a winning hand if they can be arranged in an order where the first card divided by the second card, and then divided by the third card results in an integer.

A particularly lazy child has asked you to help them out. Given the child's hand, tell them what to exclaim.

#### Input Specification

There will be one line with integers, the values of the cards in the hand.

#### Output Specification

`Ecalevol!`

or `I lost.`

depending on the outcome.

#### Sample Input 1
