One Mil Dash

<< < (3/3)

John Spikowski:
Swift

I may have found a bug with swiftc. The compiled version doesn't do the compare correctly and Middle is never printed.


--- Code: Text ---// Swift - 1mil.swift var accum = 0var milvar = 1000000 for _ in 1...1000000 {  accum += 1  milvar -= 1  if accum == milvar {    print("Middle")  }  } print("Plus:  ", accum)print("Minus: ", milvar)

John Spikowski:
Here are the 1mil challenge results.

John Spikowski:
AIR submitted an updated Bash script which is more efficient. (Thank You!) The post and the chart have been updated,

I have no plans to install Ruby or Rust. If you would like to submit an entry for these languages then either join the forum and post it or send me an e-mail to support @ raspberrybasic.org.

John Spikowski:
Ruby

I wasn't aware that Ruby comes pre-installed.


--- Code: Ruby ---# Ruby - 1mil.rb accum = 0milvar = 1000000 for x in 1..1000000  accum += 1  milvar -= 1  if accum == milvar then    puts "Middle"  endend puts "Plus:  #{accum}"puts "Minus: #{milvar}"
