Comment on Tutorial : Recursion in java By aathishankaran
Now what the hell does all this mean???
To better understand how the fact() method works, let’s go through a short example. When you compute the factorial of 3, the first call to fact() will cause a second call to be made with an argument of 2. this invocation will cause fact() to be called a third time with an argument of 2. This call will return 1, which is then be called a third time with an argument of 1. This call will return1, which is then multiplied by 2 (the value of n in the second invocation). This result (which is 2) is then returned to the original invocation of fact() and multiply by 3 ( the original value of n). This yields the answer, 6. You might find it interesting to insert println() statements into fact() which will show at what level each call is and what the intermediate answers are.
