All ways to divide array of strings into parts in JavaScript
Problem
We are required to write a JavaScript function that takes in an array of literals of at least two elements.
Our function should return all the ways to divide the array into two non-empty parts.
For instance −
For the array ["az", "toto", "picaro", "zone", "kiwi"]
The possibilities are −
"(az, toto picaro zone kiwi)(az toto, picaro zone kiwi)(az toto picaro, zone kiwi)(az toto picaro zone, kiwi)"
Example
Following is the code −
const arr = ["az", "toto", "picaro", "zone", "kiwi"];
const findAllPossiblities = (arr = []) => {
let array;
const res = [];
for(let i = 1; i < arr.length; i++){
array = [];
array.push(arr.slice(0,i).join(" "));
array.push(arr.slice(i).join(" "));
res.push(array);
};
return res;
};
console.log(findAllPossiblities(arr));Output
[ [ 'az', 'toto picaro zone kiwi' ], [ 'az toto', 'picaro zone kiwi' ], [ 'az toto picaro', 'zone kiwi' ], [ 'az toto picaro zone', 'kiwi' ] ]
