This is the 4th Video of our Playlist "Recursion : Popular Interview Problems" by codestorywithMIK
In this video we will try to solve a good Recursion problem : Integer to English Words | Story To Code | Leetcode 273 | codestorywithMIK
In this video, we will learn something very important - "How to find all subarray sums of an Array in increasing/decreasing order using heap."
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Summary :
The approach to converting a number to its English words representation involves recursive breakdown of the number into manageable parts, utilizing maps for quick lookups of word equivalents. Here's a summary of the steps:
Maps for Quick Lookups:
belowTen: Maps single digits to their word equivalents.
belowTwenty: Maps numbers from 10 to 19 to their word equivalents.
belowHundred: Maps multiples of ten from 20 to 90 to their word equivalents.
Recursive Function:
The solve method is designed to handle different ranges of numbers by breaking them down:
Numbers less than 10 are directly converted using belowTen.
Numbers less than 20 are converted using belowTwenty.
Numbers less than 100 are split into tens and units using belowHundred and belowTen.
Numbers less than 1000 are divided into hundreds and the remainder.
Higher ranges (thousands, millions, billions) are handled by dividing the number into thousands, millions, and billions, recursively processing each part and appending the appropriate scale word ("Thousand", "Million", "Billion").
Handling Special Cases:
The numberToWords method handles the special case when the input number is zero by returning "Zero".
For all other numbers, it calls the solve method to get the final word representation.
This approach ensures that the number is progressively broken down into smaller parts that can be directly translated to words, and then these parts are combined to form the complete word representation.
