mapping() method?The mapping() method is an inbuilt method in Euphoria. It sets the values found in a set A that are the same as those found in another set B to those in a final set C.
For example, if A is COUGH, B is CHo, and C is chy, then the mapping() method will give the output cOUGh. That is how this method works.
mapping(source_arg,from_set,to_set,level)
When elements from source_arg are found in from_set, it is changed to a matching element of to_set.
source_arg: This is the Euphoria object variable that will be changed/mapped.
from_set: This is a sequence of objects that contains items from the source that will be changed. These items are the ones that are actually transformed.
to_set: These are the changed forms of items from the source_args variable, which are found in the from_set.
level: This is an integer value parameter, which can be a 0 (the default) or 1. If the integer value is 0, then it implies that mapping will be done to every atom in every level of the sub-sequences. And if the integer value is 1, the mapping will only apply to the items at the first level in source_arg.
The mapping() function returns an object value that is a mapped form of the source_arg variable.
The image given below is a pictorial explanation of all that’s been said so far:
include std/sequence.eprintf(1,"%s", {mapping("COUGH", "CHo", "chy")})printf(1, "\n%s", {mapping("Educative Edpresso", "presso", "PRESS")})printf(1, "\n%s", mapping({"my name is pinky","Hello pinky"}, "yak", "YAK"))
