Transpose in ECMAScript
Take input text and output it transposed.
exercism fetch ecmascript transpose
Given an input text output it transposed.
Roughly explained, the transpose of a matrix:
is given by:
Rows become columns and columns become rows. See https://en.wikipedia.org/wiki/Transpose.
If the input has rows of different lengths, this is to be solved as follows:
- Pad to the left with spaces.
- Don't pad to the right.
Therefore, transposing this matrix:
In general, all characters from the input should also be present in the transposed output. That means that if a column in the input text contains only spaces on its bottom-most row(s), the corresponding output row should contain the spaces in its right-most column(s).
Go through the setup instructions for ECMAScript to install the necessary dependencies:
Install assignment dependencies:
$ npm install
Making the Test Suite Pass
Execute the tests with:
$ npm test
In the test suite, all tests but the first have been skipped.
Once you get a test passing, you can enable the next one by
