How to map N keywords based on delimiter

Karthik Agarwal

15y1.8k

I have N keywords which can be mapped as follows:

1,2,3,4----/5,6,7,8----/9,10,11,12----/--------

From the above line i should be able to map 1 to 5,2 to 6, 3 to 7, so on. I should also be able to map 1 to 9, 1 to 10, 1 to 11, 1 to 12 so on like that i should be able to map N number of combinations. I should make this generic in such a way that it should work with N number of combinations. Please tell me the logic how i can do this.

Thanks & Regards,
P.Karthik

Sorry, forgot it was C++ :)

Here's the same code in C++/CLI:

#include "stdafx.h"

using namespace System;

int main(array ^args)
{
String^ s = "1,2,3,4/5,6,7,8/9,10,11,12/13,14,15,16";
array^ groups = s->Split('/');
array^>^ subGroups = gcnew array^>(groups->Length);
for(int i = 0; i < groups->Length; i++)
{
subGroups[i] = groups[i]->Split(',');
}

int len = subGroups[0]->Length; // assume all the same length

for(int i = 0; i < len; i++)
{
for(int j = 0; j < groups->Length; j++)
{
if (j < len - 1)
{
Console::Write("{0} -> ", subGroups[j][i]);
}
else
{
Console::Write("{0}", subGroups[j][i]);
}
}

Console::WriteLine();
}

Console::ReadKey();
return 0;
}

ya vulpes, it worked for the case which had equal lengths. it worked for the case having different lengths also. but some where some index is causing problem hence i am getting things in the other way around sometimes.

Did that code work for the case when the lengths of each group were the same?

The reason I ask is that the loops are the other way around to what I'd expect and, because you've added a lot more code to the inner loop than in my simple example, it's difficult for me to suggest an alteration to deal with variable length groups and be confident it would work.

If the sub-groups are of different lengths, then you'll need to change the code as follows:

#include "stdafx.h"

using namespace System;

int main(array ^args)
{
array^ sa =
{
"1,2,3,4,5,6/7/9/13/XX/YY/'asas'",
"1,2,3,4/5,6,7,8/9,10,11,12/13,14,15,16",
"1,2,3,4/XX/YY"
};

for each(String^ s in sa)
{
array^ groups = s->Split('/');
array^>^ subGroups = gcnew array^>(groups->Length);

for(int i = 0; i < groups->Length; i++)
{
subGroups[i] = groups[i]->Split(',');
}

int len = subGroups[0]->Length;
int len2 = groups->Length;

for(int i = 0; i < len; i++)
{
for(int j = 0; j < len2; j++)
{
int k = Math::Min(i, subGroups[j]->Length - 1);

if (j < len2 - 1)
{
Console::Write("{0} -> ", subGroups[j][k]);
}
else
{
Console::Write("{0}", subGroups[j][k]);
}
}

Console::WriteLine();
}

Console::WriteLine();
}

Console::ReadKey();
return 0;
}

for(int i = 0; i < groups->Length; i++)
{
subGroups[i] = groups[i]->Split(',');
}

int len = subGroups[0]->Length; // assume all the same length // EDIT

for(int i = 0; i < len; i++)
{
for(int j = 0; j < groups->Length; j++)
{
if (j < len - 1)
{
Console::Write("{0} -> ", subGroups[j][i]);

This is not of equal length Vulpes and one more addition to me made for the above combination is:
the line looks like follows:
1. String^ s = " 1,2,3,4,5,6/7/9/13/XX/YY/'asas' ";
or
2. String^ s = "1,2,3,4/5,6,7,8/9,10,11,12/13,14,15,16";
or
3. String^ s = "1,2,3,4/XX/YY";

for the 1st case i should get output as combination as 1,7,9,13,XX,YY,asas and 2,7,9,13,XX,YY,asas and 3,7,9,13,XX,YY,asas and 4,7,9,13,XX,YY,asas and 4,7,9,13,XX,YY,asas and 5,7,9,13,XX,YY and 6,7,9,13,XX,YY,asas
for 2nd case output should same as we discussed in the past
for 3rd case 1,XX,YY and 2,XX,YY and 3,XX,YY and 4,XX,YY

The thing is that all are not of same length and all the things which are comma delimited should be in combination with the ones which are slash delimited.

any doubts i would be happy to clear them.

Something like this perhaps:

using System;

class Program
{
static void Main()
{
string s = "1,2,3,4/5,6,7,8/9,10,11,12/13,14,15,16";
string[] groups = s.Split('/');
string[][] subGroups = new string[groups.Length][];
for(int i = 0; i < groups.Length; i++)

{
subGroups[i] = groups[i].Split(',');
}

int len = subGroups[0].Length; // assume all the same length

for(int i = 0; i < len; i++)
{
for(int j = 0; j < groups.Length; j++)
{
if (j < len - 1)
{
Console.Write("{0} -> ", subGroups[j][i]);
}
else
{
Console.Write("{0}", subGroups[j][i]);
}
}

Console.WriteLine();
}

Console.ReadKey();
}
}
