Hi everyone - I hope your day is going great.
Can someone please kindly help me with the coding of the following function -
I have absolutely no clue where to start -
Given the following sets of numbers -
1154 1179 2154 2554 2484 2144 4515 1144 1517 4815 1481
Given the Index number of 1154
I want to search the numbers for the Index number of 1154
The search will return a True if I can find 3 or 4 same digits between the Index number and the 8 numbers
The search also have the following criteria -
meaning that -
1154 when compared to 1154 == true
1154 when compared to 1179 == false
1154 when compared to 2154 == true
1154 when compared to 2554 == false
1154 when compared to 2484 == false
1154 when compared to 2144 == false
1154 when compared to 4515 == true
1154 when compared to 1144 == true
1154 when compared to 1517 == true
1154 when compared to 4815 == true
1154 when compared to 1481 == true
the index number can also be of type - 1234, 1123, 1112, 1111
:)
Thank You

So create some function (fun(a, b)) such that,
1) 'a' creates a unique array of the input, bool[10], marking which digits exist
2) 'b' creates a unique array of the input, bool[10], which must have at least 3 elements in common
3) returns true if UNION(array_a, array_b) contains at least 3 elements
4) returns false otherwise
There are plenty of other ways to do this, I'm not saying this is the only way.
If you are given integers instead of strings, you'll want to find each digit individually,
that means you'll want to take the original integer 'a' and a while loop, eg:while( tmp_a ) bool[ tmp_a % 10 ] = true; tmp_a /= 10;
Or some such...
In the case that the uniqueness of the digit doesn't matter, you'll want to use int[10] instead of bool[10] and count the number of occurences.int[tmp_a%10]++;

Sorry, Here is what I have done so far ...
Please do not laugh ...
Somehow the Strncmp() Function is not working ...
Any help will be well appreciated ...
Thank You ...

Geez it really seems like you're overcomplicating the task, would you mind showing me the true file format of "4D database.txt"?
I'm not really a fan of your general approach to the problem, but I also don't want to tell you how to think.
To start with, can you demonstrate that the strings "FourD1char" and "FourD2char" are exactly what you expect? I see that you have print functions, but you didn't include any sample output here. I'm just some random stranger, so I need to have a little context in order to help you. =)
