已知定义在\(R\)上的函数\(f\left( x \right)\)是奇函数，且满足\(f\left( 3-x \right)=f\left( x \right)\)，\(f\left( -1 \right)=3\)，数列\(\left\{ {{a}_{n}} \right\}\)满足\({{a}_{1}}=1\)且\({{a}_{n}}=n\left( {{a}_{n+1}}-{{a}_{n}} \right)\) \(\left( n\in {{N}^{*}} \right)\)，则\(f\left( {{a}_{36}} \right)+f\left( {{a}_{37}} \right)=(\)     \()\)
