Hi, I want to preprocess the input the data. Like I have the code below

int N = ...; // the number of demands
 tuple demand {
        int index; //from 1 to N
        int ts;
        int te;
 }
 
 {demand} Dem = ...;
 int overlap[1..N][1..N] = ...;
 
 //preprocessing
 execute {
        for(var p, q in Dem) {
                if( (p.ts<=q.ts) && (p.te>q.ts)) {
                        overlap[p.index][q.index] = 1;
                }
                else {
                        overlap[p.index][q.index] = 0;
                }
        }
 }

When I run it, there is this "Bad declaration syntax." at "for(var p, q in Dem)". I don't know how to correct this, any ideas? Thanks,

Hui
