Define a <code>time</code> function that returns the elapsed time (in ms) to execute a block of code. |
|||
<lang scala> |
|||
def time(f: => Unit)={ |
|||
val s = System.currentTimeMillis |
|||
f |
|||
System.currentTimeMillis - s |
|||
} |
|||
</lang> |
|||
Can be called with a code block: |
|||
<lang scala> |
|||
println(time { |
|||
for(i <- 1 to 10000000) {} |
|||
}) |
|||
</lang> |
|||
Or with a function: |
|||
<lang scala> |
|||
def count(i:Int) = for(j <- 1 to i){} |
|||
println(time (count(10000000))) |
|||
</lang> |
