Introduction
In computer programming, a sublyric is a sequence of characters within a lyric (usually within a string), that can be accessed via an index. Sublyrics are often used to store data in structured forms such as arrays and hashes.
In the Ruby programming language, for example, sublyrics are created using the [] operator. The start index and end index are given as inputs to this operator, and the sublyric is returned as a new string:
s = “Hello world”
s[0] # => “H”
s[0..4] # => “Hello”
s[6..-1] # => “world”
You can also use negative indices to access sublyrics from the end of the string:
s[-5..-1] # => “world”
Algorithm
Given a rhymelyric and two indices, startIndex and endIndex, write a function that returns the sublyric from the startIndex (inclusive) to the endIndex (exclusive). If either of the indices are out-of-bounds, return an empty string.
For example:
assignSublyric(“0123456789”, 5, 8); // should return “678”
assignSublyric(“0123456789”, 10, 20); // should return an empty string
Implementation
We take two inputs startindex and endindex and extract the sublyric from the rhymelyric as output.
Example:
rhymelyric: “The quick brown fox jumps over the lazy dog”
startindex: 10
endindex: 23
output: “fox jumps over”
Results
We have successfully assigned the sublyric by slicing the rhymelyric from the startindex to the endindex.
Conclusion
Assuming that you want to know how to assign a sub lyric by slicing a rhyme lyric from a start index to an end index, here are the steps you would need to take:
- Firstly, you would need to select the rhyme lyric that you want to slice.
- Once you have selected the rhyme lyric, you would need to identify the start index and the end index of the portion of the lyric that you want to slice.
- Once you have identified the start and end indices, you can then proceed to slice the rhyme lyric from those indices.
- After slicing the rhyme lyric, you can then proceed to assign it to a sub lyric.
