I am so confused about the swapping value thing. Could you do the following question and also explain more about it?

Score: Sorry, you did not answer the question correctly. Answer(s): (Your response(s) are shown below.) Suppose k, m, and n are already declared int variables that hold concrete but unknown values. Suppose also that they hold the wrong values: m should hold k's value, n should hold m's value, and k should hold n's value. Write a series of assignment statements that give k, m and n their correct values. RESUBMIT ANSWER Feedback: k contains n's value m contains n's value n contains k's value
