package main

// purpose:
// init flags
// read ints from stdin
// sort ints[]
// calc quartile
// print deviant values with adaptable Tukey value
// or 3xMedian if -M is choosed

// v0.1 print green/red values
// v0.2 - dont mess original data, return 1 if found quartile deviance
// v0.3 - trim space and tabs
// v0.4 - float32 and direct input of "sort |uniq -c|sort -rn|head -nn"
// V0.5 - Adding Z-score mod méthod.
// V0.6 - Bug in getNumbers
