Question

Q-1: Write a program in Assembly language using MIPS instruction set that reads 15 integer numbers from user and stores all the numbers in the array intArray. Now, read another integer number N from the user, find the total number of array elements that are greater or equal to the number N, and the total number of array elements that are lower than the number N You must have two procedures: i. ReadIntegerArray: this procedure should read integer array elements from the user and store it in the array intArray. Argument $a0: base address of the array intArray should be passed as parameter. Return value: No need to return any value. ii. CalcDeviation: This procedure should find the total number of array elements that are greater or equal to the number N and the total number of array elements that are lower than the number N. Argument $a0: base address of the array intArray should be passed. Return value $v0: number of array elements that are greater or equal to the number N Return value $v1: number of array elements that are lower than the number N. Main part of your program should read an integer number N, call the procedure ReadIntegerArray and CalcDeviation. At the end, the program should print the values that are returned by the procedute CalcDeviation.
