What is the minsize() method in Euphoria?
Overview
In Euphoria, we use the length() method to get the size of a sequence value, which is as follows:
length(sequence_value)
This method is significant because its output can serve as a part of a condition in a conditional statement. One of these conditions is mainly because a sequence may not have a predetermined size. Hence, we can confirm the size by using an if statement. We can use the minsize() method to ensure that the sequence has a minimum required size by padding it up if less.
The minsize() method ensures that a sequence has the minimum size indicated by padding it to the right with a value as provided.
Syntax
minsize(source_data, min_size, pad_data)
Parameter
source_data: This is the value to be maintained at a specified minimum length. It is an object data type. It may need an extension to meet the minimum size if less.min_size: This is an integer value. It represents the least size the sequence should be.pad_data: This is the data added to the right side of thesource_datato make its length up to themin_sizeif it was initially less.
Return value
It returns a sequence. If the initial size is less than the min_size, this must have been padded. It will return the initial sequence unchanged if its size is greater than the min_size.
Code
Below is a sample code to use the minsize() method:
include std/sequence.eobject source_data1, source_data2sequence output1, output2source_data1 = {7,8,5,1,3,9,10}source_data2 = {2,4,8,4,5,3,4}output1 = minsize({4,3,6,2,7,1,2}, 10, -5)output2 = minsize({4,3,6,2,7,1,2}, 5, -1)print(1,output1)puts(1,"\n")print(1,output2)
Explanation
- Line 1: We will include an inbuilt module.
- Line 3–4: We declare variables that we will use later.
- Line 6–7: We will save the output from the operation of
minsize(). - Line 12-14: We print the output to the screen.
