PLEASE HELP CODE IN C LANGUAGE

Please consider the following struct definition for the following question: struct Node int data: struct Node* next }; typedef struct Node Node : typedef Node *Nodeptr: Nodeptr head. // Assume that it is a pointer to a list with many nodes. 04.(25 pts.) For this problem, you will implement the remove_all function for a Stack structure which, when called with the value val, will remov all instances of val from the stack. The top of the stack will be adjusted, if necessary void remove_a11 (Nodeptr topptr, int val) E..calling remove_all (thead, 9) from a stack with contents 19, 1, 9, 2, 3, 9, 4, 9, 9] (the top of the stack is the leftmost value shown) will result in the stack with contents [1, 2, 3, 4). remove_a11 should work correctly if the stack is empty, and may also leave the stack empty You should not change the value contained in any of the nodes nor create any new nodes. You are allowed to invoke push, pop, and isEmpty functions of the stack covered in the lectures. (You do not need to implement push, pop, and 1sEmpty functions) void push (Node Ptr topptr, int into); // insert a node to the stack int pop (Node Ptr topptr): // remove a node from the stack int isEmpty (Node Ptr topptr) // return 1 if the stack is empty. O otherwise
