Algorithm:
Two input files are given The first contains |N| ratios in the form of
two labels and a ratio:
USD, GBP, 0.69
Meter, Yard, 1.09
YEN, EUR, 0.0077
GBP, YEN, 167.75
Horsepower, Watt, 745.7
Each line A, B, C means that C is a conversion factor from A to B. In other words, mu...
Practicing hacker rank questions and would love some feedback on how I could perform optimizations on a Trie.
This code will add a bunch of names into a trie and then when asked will turn how many names belong to a partial match. eg.
jenn, jennifer, george, jenny
partial => jen
return => 3

I need the input a value then count the number of zeros, odds and evens. Im stuck on separating the numbers of the inputted value into individual digits so I can put the in an if statement. Any suggestions?
In a turn-based manner, allow the player to roll a dice (1-6) to
travel to the next location. For simplicity, we assume each number
represents travelling across 1 location and that there are 10
locations in the game, with the last location (location 10) belonging
to the lair of the bos...
Bist-o-yek (21) is a Persian card game very similar to blackjack, except it doesn't have things like double down and split. I did, though, change it a little. For example, added dealer dealing to 17.
First, there's a class called Cards that carries each card's name and score. Then, some function...

It is evident in the AWS documentation that each record in the transformed output of a fire hose data transformation must match on a recordId corresponding to an input record.
Can multiple output records point to the same input recordId?
For example, suppose 10 records enter with unique ids, e...

From my researching, I found out that an 'if' statement in google sheets should follow this format.

)
I saying if the value in cell B5 is negative, then it should prin...

I'm learning Haskell, and I've finally gotten around to coding up some Haskell. This code passed my tests.
This code takes a line from standard in which tells it how many cases it's going to have (1 to 5), and for each case, it takes a line telling it how many pairs (max of 100) of x's and y's i...
