##   Logical Type

Good job! Let's move on to the study of the following data type - logical.

Values of this data type can only take two values: `TRUE` or `T` and `FALSE` or `F`. Note that the wording is case-sensitive, i.e., `false` will not be considered a logical type.

Primarily, the logical type is used while checking certain statements. For example, if you compile something like `2 > 1`, you will receive `TRUE` since `2` is greater than `1`. This fact will be widely used a few chapters later.

You can also convert numbers and text into logical types. All the numbers but `0` will be converted into `TRUE` (otherwise `FALSE` for `0`), and strings `'F'`, `'false'`, `'False'`, and `'FALSE'` into logical `FALSE`. The same for logical `TRUE`.

Converting logical values into numerical will result in `0` for `FALSE`, and `1` for `TRUE`.

1. Assign the result of statement `19*54 > 76*13` to `logic` variable.
2. Output the value of the `logic` variable.
3. Output the type of the `logic` variable.
4. Convert the value of the `logic` variable into `integer`, and output this value. Do not use `print()` function there.
