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}

4.11 painting a wall (1) prompt the user to input integers for a wall's height and width. calculate and output the wall's area (integer). note that in this case there is a new line after each prompt. (submit for 1 point). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet (2) extend to also calculate and output the amount of paint in gallons needed to paint the wall (floating point). assume a gallon of paint covers 350 square feet. store this value in a variable. output the amount of paint needed using the %f conversion specifier. (submit for 2 points, so 3 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons (3) extend to also calculate and output the number of 1 gallon cans needed to paint the wall. hint: use a math function to round up to the nearest gallon. (submit for 2 points, so 5 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons
