One of DMOJ's oldest problems, Boolean, is coming back! Unfortunately, many users have been exploiting the problem by cheesing it with eval. This time, we've made sure not to let that happen.

Given a string $s$ $(1\le |s|\le 1000)$ consisting of a non-negative number of space-separated not directives followed by a true or false, evaluate the boolean expression.

Note: You may only submit to this problem in Python 3.

Input Specification

The first line of input contains a string $s$.

Output Specification

Output on a single line, either true or false, corresponding to the result of the boolean expression.

Scoring

Your score will be computed based on the length of your source code, the shorter the better. For an $L$-byte program,

• if $L\le 37$, you will receive the full $100$ points.
• if $38\le L\le 42$, you will receive $80-5\times (L-38)$ points.
• if $43\le L$, you will receive $\lfloor 2^{0.21(70-L)}\rfloor$ points.

Sample Input 1
