Given a vector y e Rd and a scalar A> 0, consider the following opti min 히lx-yll + 세제i. XER 2 Please derive the optimal solution of x expressed in terms of y and A (you need to show detailed steps of derivation). Hint: consider each coordinate separately, and consider separately when the optimal value is less than zero or larger than zero, and then derive a solution that covers both cases.
