1	Pass	a = [1 5 3 11 7 2 4 9]; stride = 2; assert(isequal(skip_sequence_stride(a),stride))
2	Pass	a = [1:5:20 23:3:42 2:9:100]; stride = 9; assert(isequal(skip_sequence_stride(a),stride))
3	Pass	a = [2:2:22 13:17]; a = a(randperm(length(a))); stride = 2; assert(isequal(skip_sequence_stride(a),stride))
4	Pass	a = 37:5:120; a = a(randperm(length(a))); stride = 5; assert(isequal(skip_sequence_stride(a),stride))
5	Pass	a = [1:5 101:10:171 201:205]; a = a(randperm(length(a))); stride = 10; assert(isequal(skip_sequence_stride(a),stride))
6	Pass	a = [7:17:302 primes(300)]; a = sort(a); stride = 17; assert(isequal(skip_sequence_stride(a),stride))
