+
+	Say you have a valid string of simple arithmetic that contains no unary operators (like $3!$ or $-4$) and no parenthesis:
+	$$
+	3 + 9 \times 8 \div 5 \land 6
+	$$
+
+	You may assume that all numbers and operators in this string consist of exactly one character. \\
+
+	Devise an algorithm that turns this string into a tree (as shown below), respecting the order of operations $[\land, \times, \div, +, -]$.
