The list of student marks shown in Figure 2.10 is changed to contain j test scores for each student. Assume that there are n students. Write a RISC-style program for computing the sums of the scores on each test and store these sums in the memory word locations at addresses SUM, SUM + 4, SUM + 8, . . . . The number of tests, j, is larger than the number of registers in the processor, so the type of program shown in Figure 2.11 for the 3-test case cannot be used. Use two nested loops. The inner loop should accumulate the sum for a particular test, and the outer loop should run over the number of tests, j. Assume that the memory area used to store the sums has been cleared to zero initially.
