Stable Block Arrangement

You are given an arrangement of N blocks. Each block is represented by three integers: width, height, and number. A block is considered to be sufficiently supported if the following inequality holds:

$$ \text{height} \leq \frac{\text{number}}{\text{width}} $$

The arrangement is stable if every block satisfies the above inequality, otherwise it is unstable.

Your task is to determine if the arrangement is stable. Print Stable if the arrangement is stable, or Unstable otherwise.

inputFormat

The first line contains an integer N representing the number of blocks. Each of the next N lines contains three space-separated integers: width, height, and number.

It is guaranteed that all values are positive integers.

outputFormat

Output a single line: Stable if the arrangement is stable, or Unstable otherwise.
