Select the description(s) that result in a ragged 2-d (matrix) array instantiation.
(this means that directly after the described instantiation, the matrix will be a ragged array with some row lengths being different from other row lengths in the matrix, not a matrix in which all the row lengths in are the same.)
a. a numpy 2-d array whose shape is described by a tuple, like (4, 8) or (3, 4), passed to the constructor.
b. a python list-of-lists in which not all of the inner lists are the same length.
c. a python list-of-lists in which all of the inner lists are the same length.
d. a numpy 1-d array whose individual elements point to separate numpy 1-d arrays (each of which might be a different length).

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
