\(S=\left(\frac11+\frac13+\frac15+..+\frac{1}{2015}\right)-\left(\frac12+\frac14+\frac16+\cdots+\frac{1}{2014}\right)\)
\(S=\left(1+\frac12+\frac13+\cdots+\frac{1}{2015}\right)-2\left(\frac12+\frac14+\frac16+\cdots+\frac{1}{2014}\right)\) \(S=\left(1+\frac12+\frac13+\cdots+\frac{1}{2015}\right)-\left(1+\frac12+\frac13+\cdots+\frac{1}{2007}\right)\)
\(S=\frac{1}{2008}+\frac{1}{2009}+\frac{1}{2010}+\cdots+\frac{1}{2015}\)
=>(S-P)^2024 = 0^2024 = 0
