Approximate Answer

You are solving a problem whose correct answer is the integer $Y$. The answer you obtained, however, is the integer $X$. Your answer will be considered correct if the difference between $X$ and $Y$ is at most $K$. In other words, your answer is considered correct if and only if: $$ |X-Y| \leq K $$ Given the values of $X$, $Y$, and $K$, determine whether your answer $X$ is correct or not. N
