Have you came across those online forms where you'd begin to type in a word, and it will give you suggestions as to how to end it? That's autocomplete. It matches a beginning of the word against the dictionary of known (or relevant) words, and makes suggestions. Since the dictionary that I want you guys to have will be too big for an input file, you'd have to make your own.
- Start with an array of 50,000 integers, from 0 to 49,000.
- For each element, multiply it by the sum of its digits, and take modulo 99999
- This is your dictionary
It's important that we are working with the same "words" here, so to check that you are doing this right, here's an example: If the original seed is 12345, then the resulting word is (12345 * 15) % 99999 = 85176. Here are some extra checks, at various indexes of my dictionary:
- dictionary == 0
- dictionary == 81
- dictionary == 10
- dictionary == 85176
- dictionary == 99979
The input file DATA4.txt will contain 5 lines, integers 0 <= N <= 49999, prefixes of words being entered.
The output file OUT4.txt will contain 5 integer results, number of possible matches in the dictionary; that is number of words that have the input as a prefix (begin with that sequence) or are that word in full.
Note1: words in the dictionary are not guaranteed to be unique. For example, 99990 appears in the dictionary 3 times. All 3 of them would count towards the answer.
Note2: be aware of the performance constrains. The judge will time out if you take too long.
