We use Huffman’s algorithm to obtain an encoding of alphabet {a, b, c} with frequencies fa, fb, fc. In each of the following cases, either give an example of frequencies (fa, fb, fc) that would yield the specified code, or explain why the code cannot possibly be obtained (no matter what the frequencies are).

a. Code : {0, 10, 11}
b. Code : {0, 1, 00}
c. Code : {10, 01, 00}

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.

In a game with three frames, where will the objects on layer 1 appear? a. next to the play area b. in the middle of the game c. behind everything else d. in front of everything else

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
