Calculus Level 5

$\displaystyle\int _{ 0 }^{ 1 }{ \int _{ 0 }^{ 1 }{ \left\{ \dfrac { k }{ x-y } \right\} \left\{ \dfrac { 1 }{ x } \right\} \left\{ \dfrac { 1 }{ y } \right\} \, dx\; dy } } =\dfrac { H }{ U } (M-{ M }_{ 1 }\gamma ^{ U_{ 1 } })^{ S }$

Let $$k$$ be a positive real number that satisfy the equation above, where $$H,U,M,M_1,U_1,S$$ are positive integers and $$H,U$$ coprime.

Find $$H+U+M+M_1+U_1+S$$.
