Hello all the forum users, I want to construct a matrix for different IDs having "1" values at variables lying in the interval of the given data and "0" otherwise. Example: THe input data will be like this

A 1  2  
A 7  10 
A 15 20 
B 3  5  
B 11 15  
C 5  10  
D 10 20

The headers will be different values of no relation to each other, I have input them in the @array e.g @array = (1 , 2, 3 , 5 , 7, 10 , 11, 15 , 20)

I want all the IDs (A, B, C, D) to be in one output file, but each in only one line: Aim 

ID 1 2 3 5 7 10 11 15 20 
A  1 1 0 0 1 1  0  1  1 
B  0 0 1 1 0 0  1  1  0 
C  0 0 0 1 1 1  0  0  0 
D  0 0 0 0 0 1  1  1  1

So, all the vlaues will be "map" to the arrays but do not know how to look further to see if the Id is coming again, hence put 1 in the corrsponding variables instead of 0? (Id could be repeated with different values for up to 100 times! or more no fixed rule)

I tried to work it out but seems too hard for me!! Thanks,
