Chapter 1.4, Problem 4QE
Explanation of Solution
- “LeD or incandescent bulb”, is the device that can have two states, ON and OFF.
- When the current flows through the circuit, the bulb is ON and it indicates a high state.
- When the switch is OFF, there is no current in the circuit and the device is OFF and it indicates a low state.

The Famous Gauss
You must know about Gauss, the famous mathematician. Back in late 1700’s, he was at elementary school. Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher. He amazed his teacher with how quickly he found the sum of the integers from 1 to 100 to be 5050. Gauss recognized he had fifty pairs of numbers when he added the first and last number in the series, the second and second-last number in the series, and so on. For example:(1 + 100), (2 + 99), (3 + 98), ..., (50 + 51). Each pair has a sum of 101 and there are 50 pairs. History repeats itself. Jojo’s teacher assign a “busy work” to the students. The teacher believes that there will be no shortcut to finish this task in a minute. The teacher gives N integers A1, A2, ..., AN to the students. The teacher also gives Q questions. Each question contains two integers L and R asking the sum of all Ai where L <= Ai <= R. As a good friend of Jojo, help Jojo…

The CMPT215Float16 representation follows the IEEE 754 binary floating point standard, but with smaller-sized fields for the exponent and fraction. In particular, CMPT215Float16 numbers have a 1-bit sign field, followed by a 7-bit exponent field (in biased notation, with a bias of only 63 because of the smaller size of this field), followed by an 8-bit fraction field.

An RGB tuple is composed of three numbers that specify the intensity of each color. Because it uses 8 bits (0s or 1s) for each color, each intensity can be transformed into a hexadecimal number with two digits at most. There are 256 possible shades for each color, since "11111111" (or hex "ff") corresponds to decimal 255, plus the number 000. The combination of all 256 possible shades for the three primary colors gives 256 cubed, or over 16 million possible colors. Write a function that takes a color in RGB or hex and returns the opposite. If it takes in the three integers in an RGB, it should return a string with the equivalent hexadecimal notation, plus a hash sign (#) at the front. If it takes in a string in hex, it should return an array with the three integers corresponding to RGB. Examples rgbHex (150, 50, 76) "#96324c" // 150 is hex 96, 50 is hex 32 and 76 is hex 4c. - rgbHex("#303749") → (48,…arrow_forward
