Implement, using only the Queue kernel methods, the static method declared as follows and answer the questions below: Reports the smallest integer in the given {@code Queue). @param q the queue of integer @return the smallest integer in the given queue @requires q /= empty_string @ensures min is in entries (q) and for all x: integer where (x is in entries (q)) (min <= x) ivate static int min (Queue q) {...} i. Why do you need the requires clause? ii. Why is the first line of the ensures clause important (min is in entries (q))? Explain what the implementation could do if this line was not included in the postcondition.
