Hi, Jamil Kasan. Could you please also block the hack demonstrated in "Solution 1421065"? A few other submissions including "Solution 1065619", and "Solution 1274309" are not strictly following the indication in the title to use _only_ sine. At time of writing goc3 has the smallest fully compliant submission ("Solution 1042965") [why didn't I think of this!] by my interpretation of the Problem. —DIV
