(20 points) Below is a snippet from a Checkers game program in C.
```
void setKing(int row, int col, int isKing)
{
  int* rowAddr = getRowAddr(row); //returns the memory address of row
  rowAddr[col] = isKing;
}
```
Fill in the missing portions of the setKing function below, adhering to the RISC-V procedure call conventions. You should assume setKing is called according to RISC-V convention. Do not implement getRowAddr, assume it is already implemented following the conventions. You are encouraged to use register names (e.g. t0) instead of register ids (e.g. x5) in this code.
```
setKing:   #entry point to setKing procedure
```
```
jal ra, getRowAddr  #call to getRowAddr
```
```
jalr    x0, 0(ra)   #return form setKing
```
