# Word Conversion

posted 4 years ago

First you figure out how to do it "manually", without Java or any other programming language. You write down the steps--very basic, simple, precise, well-defined steps--with pencil and paper, and then you step through them by hand, and then when you find out you made some mistakes, you erase, and you correct, and you try again, and you repeat this process until you're pretty sure you have it right.

Then you convert those steps from English (or whatever language you're most comfortable with) into Java, and if collections and/or generics are a good fit for that conversion, you use them, and if not, you don't.

Also remember the value of a three-digit number is the value of the two-digit number with “howeverMany hundred” added. So you don’t need the > 100 test.

You would add spaces and “and” or hyphens (eg twenty-three) as appropriate.

I do not think you should put eleven, twelve, thirteen in the units Map; they need to be in a Map by themselves possibly called teens, because eleven to nineteen are pronounced differently from other numbers over ten.

I think you might need another Map with “hundred”, “thousand”, “million”, or similar in.

Back to your pencil and paper. You can use / and % repeatedly. But you would require a loop.Dishant Verma wrote: . . . "I have used this. But it is upto 99,999. But I want to enter any number having length 'n'....

And How can I eliminate if-else to make it more standardise.?"

You are going to have to define what the max. of 'n' is, since there is no limit to the number someone can put in. For example, I could (theorieticaly) input a number that has a thousand digits. Do you really want to be able to handle that? I'm not even sure there are words for number that big...

Googolplex anyone?

The biggest named number that's ever actually been

Campbell Ritchie wrote:Last time I looked in theGuiness Book of Records, they said the largest named number was the centillion, which has 601 digits.

Googolplex anyone?

The biggest named number that's ever actually been

*used*for something that I've ever heard of is Graham's Number. If we try to express it in scientific notation, the number of digits in the

*exponent*is more than the number of atoms in the universe. (I think I'm actually even grossly understating there, but it's something along those lines.)

I'm pretty sure they don't all have names up to a googleplex, and this Graham's ?Number (which I had not heard of before) would be further proof you can't have names for all of them...

If it were me, I'd start by calling toString on the Integer. Then I'd read the String right to left a character at a time. This would require no math at all; the position of the character would tell me tens, hundreds, thousands.

But I agree completely with Campbell and Jeff: work it all out on paper first.

Actually, I seem to remember that when 'Googol' was named, it had something to do with the number of protons in the known universe. But now, thanks to Hubble etc, it's probably a few hundred Googol. Perhaps we should just call it a 'Hubble' and let the IAU estimate it every year for us: Jobs for the boys, no?

This is true, but you get into some oddities with number like "13". You don't want "13,000" to come out as "ten thousand three thousand"

That goes back to the whole "work it out on paper" bit.

Sorry for bumping this topic, but... I am currently playing with a non-Java based tool, remembered this topic, and wondered if I can configure it to do this very task. And of course, to tackle that thousand digit number.

Anyway, according to my testing, this thousand digit number ...

Technically, a "Googol" is not a useable number for this... why? A googol is 10^100 which is not needed as only every three digits need a name. The names around the googol are "duotrigintillion" (which is 10^99), and "trestrigintillion" (which is 10^102).

As for "Googolplex", which is ten to the googol, that too, is not a useable number -- as a googol is also not divisable by three (and kudos to those who knows how I was able to determine that in my head ).

Also, you should distinguish between a requirement and implementation detail. There is nothing in the requirement that says that there is a limit to the size.... Of course, one of the requirements was to use Java -- which I didn't do...
