Consider a database with objects X and Y and assume that there are two transactions T$1$ and T$2.$ Transactions T$1$ reads objects X and Y and then writes object X$.$ Transactions T$2$ reads objects X and Y and then write objects X and Y$.$

$($a$)$ Give an example schedule with actions of transactions T$1$ and T$2$ on objects X and Y that results in a write$-$read conflict.
