@Chad There are two inputs, the word to be tested and the dictionary containing all English words

ok

thanks

@Chad If the word to be tested contains a word of every length up to its own length, you output True, otherwise False

Chad

9:06 PM

I go to work on it

So "cat" would be True, because "a", "at" and "cat" are all words

Same for "goat"

Emmet (alt spellings emmit or emit) is a pejorative nickname that some Cornish people use to refer to the non-Cornish. It originally referred to tourists who visit Cornwall but has also been used by native Cornish Folk to refer to "incomers" or residents who have moved to the county but were not born there. The more usual term "blowins" is used by the Cornish to describe new residents from outside Cornwall. The related terms Overner and Overlander are used on the Isle of Wight to refer to outsiders from the mainland, who are viewed with similar levels of suspicion. == Etymology == It is commonly...

Chad

You can use string letter (A, B, C) and numbers from 1 to 26.

Leaky Nun

I'm being the master of irony again

Nathan Merrill

@Chad I'd recommend writing out that if the input is invalid (too big number or not an uppercase letter), they should output "0"

Adnan

@Chad So, the input will always be an alphabetic character, or a number in the range 1 - 26?

Nathan Merrill

or, remove the test case

Chad

9:56 PM

Yes

Helka Homba

"Just letters uppercase are allowed." In the output? Input? Code?

quartata

He means you only have to handle the uppercase alphabet obviously

I don't think it's unclear at all

Chad

@HelkaHomba Just letters uppercase are allowed in input and output (You can't output b and you can't input b).
