MDP Rewards

We used a reward function $R(s,a,s^{\text{'}})$ in our definition of MDPs$.$ Sometimes, the reward function is

given as $R(s,a)$ instead. Explain how to define a reward function $R(s,a)$ which leads to an equivalent

problem to the one defined by $R(s,a,s^{\text{'}}).($Hint: how can you define $R(s,a)$ so that it does not change

the values $/$ q$-$values in the Bellman equation?$)$
