Ana, Beto, and Carla are playing a Tournament of Alliances with Points. Each of them has a score, and two of them will ally to form a duo. If the sum of the points of the allies exceeds the points of the third player, the duo wins. Otherwise, the other player wins alone.

Given the scores of the players, can someone win alone?

Input

A line with 3 positive integers $$$A$$$, $$$B$$$, and $$$C$$$ $$$(1 \leq A,B,C \leq 100)$$$ indicating the scores of Ana, Beto, and Carla respectively.

Output

A line with the letter "S" if someone can ensure a win alone, or the letter "N" otherwise.
