Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. There are well-known formulas: <image>, <image>, <image>. Also mathematicians found similar formulas for higher degrees. Find the value of the sum <image> modulo 109 + 7 (so you should find the...
