色々な言語でたらい回し関数の速度を比較してみた

# たらい回し関数

「たらい回し関数」として知られる [竹内関数](https://ja.wikipedia.org/wiki/%E7%AB%B9%E5%86%85%E9%96%A2%E6%95%B0) を色々な言語で動かして、完了するまでの時間を測ってみました。

[色々な言語で計算速度を比較してみた](https://qiita.com/hanaata/items/c91788bcac2a40f1bb05) の記事を読んだことがあり、似たようなことをやってみたいと思ってました。

$ s7c -?
SEED7 COMPILER Version 3.2.50 Copyright (c) 1990-2023 Thomas Mertes
usage: s7c [options] source

Options:
  -?   Write Seed7 compiler usage.
  -On  Tell the C compiler to optimize with level n (n is between 1 and 3).
  -O   Equivalent to -O1
  -S   Specify the stack size of the executable (e.g.: -S 16777216).
  -b   Specify the directory of the Seed7 runtime libraries (e.g.: -b ../bin).
  -c   Specify configuration (C compiler, etc.) to be used (e.g.: -c emcc).
  -e   Generate code which sends a signal, if an uncaught exception occurs.
       This option allows debuggers to handle uncaught Seed7 exceptions.
  -flto Enable link time optimization.
  -g   Tell the C compiler to generate an executable with debug information.
       This way the debugger will refer to Seed7 source files and line numbers.
       To generate debug information which refers to the temporary C program
       the option -g-debug_c can be used.
  -l   Add a directory to the include library search path (e.g.: -l ../lib).
  -ocn Optimize generated C code with level n. E.g.: -oc3
       The level n is a digit between 0 and 3:
         0 Do no optimizations with constants.
         1 Use literals and named constants to simplify expressions (default).
         2 Evaluate constant parameter expressions to simplify expressions.
         3 Like -oc2 and additionally evaluate all constant expressions.
  -p   Activate simple function profiling.
  -sx  Suppress checks specified with x. E.g.: -sr or -sro
       The checks x are specified with letters from the following list:
         d Suppress the generation of checks for integer division by zero.
         i Suppress the generation of index checks (e.g. string, array).
         o Suppress the generation of integer overflow checks.
         r Suppress the generation of range checks.
  -tx  Set runtime trace level to x. Where x is a string consisting of:
         d Trace dynamic calls
         e Trace exceptions and handlers
         f Trace functions
         s Trace signals
  -wn  Specify warning level n. E.g.: -w2
       The level n is a digit between 0 and 2:
         0 Omit warnings.
         1 Write normal warnings (default).
         2 Write warnings for raised exceptions.
