2.3 Time complexity The time taken by a program p is t(p) T(p=compile timetrun time The compile time does not depend on the instance characteristics The run time is denoted by t(instance characteristics) D)operation counts identify one or more key operations and determine the num ber of times these are performed2.3 Time complexity The time taken by a program p is T(p) T(p)=compile time+run time The compile time does not depend on the instance characteristics The run time is denoted by tp (instance characteristics) 1)operation counts identify one or more key operations and determine the number of times these are performed
