2.5) The new Christmas scheme worked so well that Ariel, Shanice, Isaac, and Tyrone decided to try it also. They decided that no
person would receive a gift from the person to whom s/he gave
one. Unbeknownst to the others, each friend decided to give a
gift card, but each chose a different kind. In addition, none of the
friends gave or received a gift card that shared its first letter with
his or her name. The person to whom Ariel gave a card was the
person who gave the Starbucks gift. The other three cards were for
Amazon, iTunes, and Target. The person whose name begins with
the same letter as the card that Shanice gave was the person who
received the Target card from the friend whose name begins with
the same letter as the gift that Shanice received. Who gave what
card to whom?
