Given: struct STACK INF_RC i[30]; int top; }; Assume that the following functions have already been declared and are available for use: createstack(s) pop(s, item) push(s, item) top(s, item) empty(s) + Boolean function use some or all of them to write the complete definition code for a function that passes in a stack (as an argument), removes the SECOND item (from the top) in the stack, and returns it (as an argument). You may assume that there are at least two iteras in the stack). Example: 7 top of stack returns: 8 8 7 3 3 5 5 4 4 10 points
