Using basic MIPS operation only

Write the MIPS for the function with the following signature: int getsum(int B[], int start, int end). This function will calculate the sum of all the values within array B between start and end indexes. The size of the array B is K, the base address of B in $a0. The return value will be stored in $v0. Using basic MIPs operations only (add, sub, addi, lw, beq....)
