Answer- 

The reaction of fluorine with water-

2F_{2}+2H_{2}O\rightarrow 4HF+O_{2}

F_{2}(0)\rightarrow H^{+1}F^{-1} -----------reduction (O.N of F changes from 0 to -1)

H^{+1}_{2}O^{-2}\rightarrow O_{2}^{0}   ------------- Oxidation( O.N of O changes from -2 to 0)

Fluorine reduced by gaining an electron and water oxidized by losing an electron.
