Function Documentation

◆ do_interpolation()

static std::string do_interpolation ( const std::string &  str,
const variable_set set 

◆ edit_distance_approx()

int edit_distance_approx ( const std::string &  str_1,
const std::string &  str_2 

Approximately calculates the distance between two strings.

Inspired in the Levenshtein distance, but made simpler to avoid using recursion and wasting resources.

The consequence is that the function gets "lost" after two consecutive differences.

str_1First string to compare
str_2Second string to compare
