Determining full house in poker - JavaScript
The “full house in poker” is a situation when a player, out of their five cards, has at least three cards identical. We are required to write a JavaScript function that takes in an array of five elements representing a card each and returns true if there's a full house situation, false otherwise.
Example
Following is the code −
const arr2 = ['K', '2', 'K', 'A', 'J'];
const isFullHouse = arr => {
const copy = arr.slice();
for(let i = 0; i < arr.length; ){
const el = copy.splice(i, 1)[0];
if(copy.includes(el)){
copy.splice(copy.indexOf(el), 1);
if(copy.includes(el)){
return true;
}
}else{
i++;
}
};
return false;
};
console.log(isFullHouse(arr1));
console.log(isFullHouse(arr2));Output
Following is the output in the console −
true false
