Sibac impl

Created with <3 with dartpad.dev.

main.dart

import "dart:math";
void main() {}
bool isEfficientToShorten(int len, int count, [int margin = 0]){
  if(len<0||count<0||margin<0){
    throw Error();
  }
  int repPadLen = log10(len).ceil()+log10(count).ceil()+3;
  return repPadLen<len*(count-1)+margin;
}
double log10(num x)=>log(x)/log(10);
