IN MIPS ASSEMBLY!!!

Ilsum$()$ Write a recursive function to sum the cells in a linked list. The linked list sum function takes one argument, a pointer to the first cell in a linked list, and should return the sum of all of the cells in the list.

The list resides in memory, and each cell is $8$ B in size. The first $4$B is an integer containing the value of the cell. The second $4$B is a pointer to the next cell in the linked list. The last cell in the list has a null next pointer $($i$.$e$.,$ next pointer $\backslash (=0\backslash )).$ Cell values may be positive or negative.
