Bitmap Holes- Coderbyte Have the function BitmapHoles(strArr) take the array of strings stored in strArr, which will be a 2D matrix of 0 and 1’s, and determine how many holes, or contiguous regions of 0’s, exist in the matrix. A contiguous region is one where there is a connected group of 0’s going in one or more of…

Stock Picker – Coderbyte Have the function StockPicker(arr) take the array of numbers stored in arr which will contain integers that represent the amount in dollars that a single stock is worth, and return the maximum profit that could have been made by buying stock on day x and selling stock on day y where y > x. For example: if arr is [44, 30, 24, 32, 35,…

Coderbyte – Fibonacci Checker Have the function FibonacciChecker(num) return the string yes if the number given is part of the Fibonacci sequence. This sequence is defined by: Fn = Fn-1 + Fn-2, which means to find Fn you add the previous two numbers up. The first two numbers are 0 and 1, then comes 1, 2, 3, 5 etc.…

Coderbyte – Most Free Time Have the function MostFreeTime(strArr) read the strArr parameter being passed which will represent a full day and will be filled with events that span from time X to time Y in the day. The format of each event will be hh:mmAM/PM-hh:mmAM/PM. For example, strArr may be [“10:00AM-12:30PM”,”02:00PM-02:45PM”,”09:10AM-09:50AM”]. Your program will have to output the longest amount of…

Coderbyte – Coin Determiner Have the function CoinDeterminer(num) take the input, which will be an integer ranging from 1 to 250, and return an integer output that will specify the least number of coins, that when added, equal the input integer. Coins are based on a system as follows: there are coins representing the integers 1, 5, 7, 9,…

Coderbyte – Caesar Cipher Have the function CaesarCipher(str,num) take the str parameter and perform a Caesar Cipher shift on it using the num parameter as the shifting number. A Caesar Cipher works by shifting each letter in the string N places in the alphabet (in this case N will be num). Punctuation, spaces, and capitalization should remain intact. For example if the…

Coderbyte – Letter Count Have the function LetterCount(str) take the str parameter being passed and return the first word with the greatest number of repeated letters. For example: “Today, is the greatest day ever!” should return greatest because it has 2 e’s (and 2 t’s) and it comes before ever which also has 2 e’s.…

Coderbyte – Calculator Have the function Calculator(str) take the str parameter being passed and evaluate the mathematical expression within in. For example, if str were “2+(3-1)*3” the output should be 8. Another example: if str were “(2-0)(6/2)” the output should be 6. There can be parenthesis within the string so you must evaluate it properly…

Coderbyte Blackjack Highest Have the function BlackjackHighest(strArr) take the strArr parameter being passed which will be an array of numbers and letters representing blackjack cards. Numbers in the array will be written out. So for example strArr may be [“two”,”three”,”ace”,”king”]. The full list of possibilities for strArr is: two, three, four, five, six, seven, eight,…

CoderbyteCheck Nums Have the function CheckNums(num1,num2) take both parameters being passed and return the string true if num2 is greater than num1, otherwise return the string false. If the parameter values are equal to each other then return the string -1.
