Problem Statement  
In some forms of geometry, like the kind used in geographical longitude/latitude measurements, angles are measured in base60. The base unit is the degree. One degree contains 60 minutes, and one minute contains 60 seconds. You will be given the measurement of an angle in degrees, minutes, and seconds. Return the given angle in radians. Note that n degrees is equal to n*PI/180 radians.  
Definition  
 
Notes  
  The return value must have an absolute or relative error less than 1e9.  
Constraints  
  degrees will be between 0 and 359, inclusive.  
  minutes will be between 0 and 59, inclusive.  
  seconds will be between 0 and 59, inclusive.
