# DIFFICULTY:

Cakewalk

# PREREQUISITES:

None

# PROBLEM:

You have an X-sided die that has the first X multiples of K written on it.  
Given Y, decide if it’s possible for the die to show it when rolled.

# EXPLANATION:

Y can be shown only if it’s among the first X multiples of K.

This means:

1. Y should be a multiple of K, and
2. \frac{Y}{K} should not exceed X.

In most languages, the first condition can be checked as `y % k == 0` and the second condition as `y/k <= x`.  
If both conditions are true, the answer is `Yes`, otherwise the answer is `No`.

# TIME COMPLEXITY:

\mathcal{O}(1) per testcase.

# CODE:

> x, k, y = map(int, input().split())
> print('Yes' if y%k == 0 and y//k <= x else 'No')
