Good morning! Here's our prompt for today.

We're given a string and need to see if it can be broken down into words from a dictionary array. For example:

1const str = "applecomputer";
2const dictArr = ["apple", "computer"];
3stringBreakdown(str, dictArr);
4// true

Assuming that there are no repeats in the dictionary array, can you write a method that will return true if the string can be broken down into words from the array, or false if not?

Constraints

• Length of the string <= 1000
• The string is made up of ASCII characters (all or some of it)
• Expected time complexity : O(n^2)
• Expected space complexity : O(n)

Try to solve this here or in Interactive Mode.
