Define the SLL member function Int speciaDecrement(int v), which finds the last node whose value is a multiple of 5 and replaces the value in the node before it with v. If no value in the list is a multiple of 5, or if the only multiple of 5 is value is in the first node, then the function does no decrement and returns -77. For example, if the list was [15, 24.9, 30, 11]. then after executing speciaDecrement(4), it will become (15,24,5,30.111 and the function returns 9. Also, if the list was [20,7,54,171, then after executing speciaDecrement( 4), the list remains [20.7,54,17] and the function returns -77. Below is the SLL API you are allowed to use to solve this question: class SLLE private: Nodeh://stores the address of the first cell in the list Nodet://stores the address of the last cell in the list public: //constructors SLLO); --SLLO
