This is a personal straight forward study strategy to get confortable with data structures algorithms using programming languages I already use in my carreer and the ones I'm still learning on free times.
Use NodeJS to execute index.js files
$\ node ./javascript/{algorithm-name}/index.js
Use GCC to compile ***.c files
$\ gcc ./c/{algorithm-name}.c -o {algorithm-name}
then execute program
$\ ./c/{algorithm-name}
