Suppose you have three stacks s1, s2, s3 with starting configuration shown on the left, and finishing condition shown on the right. Give a sequence of push and pop operations that take you from start to finish. You can use any of the stacks to store intermediate values. For example, to pop the top element of s1 and push it onto s3, you would write s3.push( s1.pop()).
