Given a number from 0 to 999,999,999,999, spell out that number in English.
Step 1
Handle the basic case of 0 through 99.
If the input to the program is 22, then the output should be 'twenty-two'.
Your program should complain loudly if given a number outside the blessed range.
Implement a clock that handles times without dates.
You should be able to add minutes to it.
Two clocks that represent the same time should be equal to each other.
It's a 24 hour clock going from "00:00" to "23:59".
To complete this exercise you need to define the data type Clock and implement the functions:
Given a phrase, count the occurrences of each word in that phrase.
For the purposes of this exercise you can expect that a word will always be one of:
When counting words you can assume the following rules:
Clean up user-entered phone numbers so that they can be sent SMS messages.
The North American Numbering Plan (NANP) is a telephone numbering system used by many countries in North America like the United States, Canada or Bermuda. All NANP-countries share the same international country code: 1.
NANP numbers are ten-digit numbers consisting of a three-digit Numbering Plan Area code, commonly known as area code, followed by a seven-digit local number. The first three digits of the local number represent the exchange code, followed by the unique four-digit number which is the subscriber number.
The format is usually represented as
(NXX)-NXX-XXXX
If you want to build something using a Raspberry Pi, you'll probably use resistors. For this exercise, you need to know two things about them:
In this exercise you are going to create a helpful program so that you don't have to remember the values of the bands. The program will take color names as input and output a two digit number, even if the input is more than two colors!
The band colors are encoded as follows:
Given a year, report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
on every year that is evenly divisible by 4
except every year that is evenly divisible by 100
unless the year is also evenly divisible by 400
