# The Benchmark module provides methods to measure and report the time
# used to execute Ruby code.
#
# * Measure the time to construct the string given by the expression
# <code>"a"*1_000_000_000</code>:
#
# require 'benchmark'
#
# puts Benchmark.measure { "a"*1_000_000_000 }
#
# On my machine (OSX 10.8.3 on i5 1.7 GHz) this generates:
#
# 0.350000 0.400000 0.750000 ( 0.835234)
#
# This report shows the user CPU time, system CPU time, the sum of
# the user and system CPU times, and the elapsed real time. The unit
# of time is seconds.
#
# * Do some experiments sequentially using the #bm method:
#
# require 'benchmark'
#
# n = 5000000
# Benchmark.bm do |x|
# x.report { for i in 1..n; a = "1"; end }
# x.report { n.times do ; a = "1"; end }
# x.report { 1.upto(n) do ; a = "1"; end }
# end
#
# The result:
#
# user system total real
# 1.010000 0.000000 1.010000 ( 1.014479)
# 1.000000 0.000000 1.000000 ( 0.998261)
# 0.980000 0.000000 0.980000 ( 0.981335)
#
# * Continuing the previous example, put a label in each report:
#
# require 'benchmark'
#
# n = 5000000
# Benchmark.bm(7) do |x|
# x.report("for:") { for i in 1..n; a = "1"; end }
# x.report("times:") { n.times do ; a = "1"; end }
# x.report("upto:") { 1.upto(n) do ; a = "1"; end }
# end
#
# The result:
#
# user system total real
# for: 1.010000 0.000000 1.010000 ( 1.015688)
# times: 1.000000 0.000000 1.000000 ( 1.003611)
# upto: 1.030000 0.000000 1.030000 ( 1.028098)
#
# * The times for some benchmarks depend on the order in which items
# are run. These differences are due to the cost of memory
# allocation and garbage collection. To avoid these discrepancies,
# the #bmbm method is provided. For example, to compare ways to
# sort an array of floats:
#
# require 'benchmark'
#
# array = (1..1000000).map { rand }
#
# Benchmark.bmbm do |x|
# x.report("sort!") { array.dup.sort! }
# x.report("sort") { array.dup.sort }
# end
#
# The result:
#
# Rehearsal -----------------------------------------
# sort! 1.490000 0.010000 1.500000 ( 1.490520)
# sort 1.460000 0.000000 1.460000 ( 1.463025)
# -------------------------------- total: 2.960000sec
#
# user system total real
# sort! 1.460000 0.000000 1.460000 ( 1.460465)
# sort 1.450000 0.010000 1.460000 ( 1.448327)
#
# * Report statistics of sequential experiments with unique labels,
# using the #benchmark method:
#
# require 'benchmark'
# include Benchmark # we need the CAPTION and FORMAT constants
#
# n = 5000000
# Benchmark.benchmark(CAPTION, 7, FORMAT, ">total:", ">avg:") do |x|
# tf = x.report("for:") { for i in 1..n; a = "1"; end }
# tt = x.report("times:") { n.times do ; a = "1"; end }
# tu = x.report("upto:") { 1.upto(n) do ; a = "1"; end }
# [tf+tt+tu, (tf+tt+tu)/3]
# end
#
# The result:
#
# user system total real
# for: 0.950000 0.000000 0.950000 ( 0.952039)
# times: 0.980000 0.000000 0.980000 ( 0.984938)

# Invokes the block with a Benchmark::Report object, which
# may be used to collect and report on the results of individual
# benchmark tests. Reserves +label_width+ leading spaces for
# labels on each line. Prints +caption+ at the top of the

# If the block returns an array of

# additional lines of output. If +labels+ parameter are
