[c++] How to use clock() in C++

you can measure how long your program works. The following functions help measure the CPU time since the start of the program:

  • C++ (double)clock() / CLOCKS PER SEC with ctime included.
  • python time.clock() returns floating-point value in seconds.
  • Java System.nanoTime() returns long value in nanoseconds.

my reference: Algorithms toolbox week 1 course part of data structures and algorithms specialization by University of California San Diego & National Research University Higher School of Economics

so you can add this line of code after your algorithm

cout << (double)clock() / CLOCKS_PER_SEC ;

Expected Output: the output representing the number of clock ticks per second
