$${{x}^{2}}-53x+196=\left( x-4 \right)\left( x-49 \right)$$，  当$$x\textless{}4$$或$$x\textgreater49$$时，$${{x}^{2}}-53x+196\textgreater0$$，$$f\left( x \right)=2\left( {{x}^{2}}-53x+196 \right)$$；  当$$4\leqslant x\leqslant 49$$时，$${{x}^{2}}-53x+196\leqslant 0$$，$$f\left( x \right)=0$$．  $$f\left( 1 \right)+f\left( 2 \right)+f\left( 3 \right)+f\left( 50 \right)=330$$． 
已知函数$$f\left( x \right)={{x}^{2}}-53x+196+\left\textbar{} {{x}^{2}}-53x+196 \right\textbar$$，则$$f\left( 1 \right)+f\left( 2 \right)+\cdots +f\left( 50 \right)=$$．
