Figure 1 shows a logic circuit.

Write a Boolean expression that represents the logic circuit shown in Figure 1.

You must use correct Boolean operators (such as AND, OR, NOT or equivalent symbols like $⋅\cdot$ , $+$ , $blank‾\overline{\text{blank}}$ / $∧\wedge$ , $∨\vee$ , $¬\neg$ ) in your expression.

Logic circuit diagram with inputs P, Q, and R. Inputs P and Q are connected to the inputs of an OR gate. Input R is connected to the input of a NOT gate. The output of the OR gate and the output of the NOT gate are connected to the inputs of an AND gate. The output of the AND gate is labeled S.
