LetN be the set of natural numbers and two functions f and g be defined as $$ f, g: N \rightarrow N $$ such that$$f ( n ) = \left\{ \begin{array} { l l } { \frac { n + 1 } { 2 } } & { \text { if } n \text { is odd } } \\ { \frac { n } { 2 } } & { \text { if } n \text { is even } } \end{array} \right.$$and $$ g ( n ) = n - ( - 1 ) ^ { n } . $$ Then fog is :
