Triangles with gap

#define WIDE 9

//to do this for obshii case, with SIZE and GAP, even SIZE, vertical GAP, horis GAP
//columns_gap, rows_gap

//this one is really easy now to change into summarasing array elements in
//particular triangle are of array

//seems that HIGH and WIDE was bad name choice even for particular case, have
//to check it - how fast will i rewrite this programm with different var names
