Derive a minimal SOP expression for the output $f$ in terms of inputs $A,B,C,D.$ Note that one product term is already given to you. $f=A^{\text{'}}BC{C}^{\text{'}}D+$ type your answer...

$($Use $x^{\text{'}}$ to denote the negation of X$,$ please $(1)$ write literals in UPPER case and in alphabetical order, $(2)$ omit AND symbol; $(3)$ avoid whitespace$)$

The K$-$map of this expression $f$ has square$($s$)$ of $1.$
