Assume that you have an array of integers named arr.
the following program segment is intended to sum arr [0]through arr[n−1], where n = arr. length:

sum = 0;
i = 0;
n = arr. length;
while (i ! = n)
{
i++;
sum += arr[i];
}
in order for this segment to perform as intended, which of the following modifications, if any, should be made?

a) no modification is necessary
b) sum = 0; i = 0; should be changed to sum = arr[1]; i = 1;
c) while (i ! = n) should be changed to while (i < = n)
d) sum += arr[i]; should be changed to sum += arr[i+1];
e) i++; should be interchanged with sum += arr[i];

Write a program in plp assembly that counts up by one starting from zero (or one) inside a loop and writes this value to the leds every time the value is increased. the memory address of the leds is 0xf0200000. the table below shows the meaning and an example usage of the instructions covered in the video, plp instructions for project 1. instruction example usage meaning load immediate li $t0, 8 register $t0 is set to the value, 8. store word sw $t2, 0($t1) the value in register $t1 is used as the memory address. the value in register $t2 is copied into this memory address. add addiu $t4, $t3, 29 register $t4 is assigned the sum of 29 and the value in register $t3. jump j your_label_name the program jumps to the line following the label, "your_label_name: ". label your label name: defines a label called "your_label_name: " that can be jumped to
