This can also be done with a pairwise reduction, but another good way (and more performant without special support in the interpreter) is to add the element and then use windows matching the original length. Here both methods are used to invert <code><span class='Function'>+</span><span class='Modifier'>`</span></code>, which requires we take pairwise differences starting at initial value 0.</p> <pre> <span class='Function'>-</span><span class='Modifier'>˜´˘</span><span class='Number'>2</span><span class='Function'>↕</span><span class='Number'>0</span><span class='Function'>∾</span> <span class='Function'>+</span><span class='Modifier'>`</span> <span class='Number'>3</span><span class='Ligature'>‿</span><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>1</span><span class='Ligature'>‿</span><span class='Number'>1</span> ⟨ 3 2 1 1 ⟩ - <span class='Paren'>((</span><span class='Function'>-</span><span class='Modifier'>˜´</span><span class='Function'><</span><span class='Modifier'>˘</span><span class='Paren'>)</span><span class='Function'>≠↕</span><span class='Number'>0</span><span class='Function'>∾⊢</span><span class='Paren'>)</span> <span class='Function'>+</span><span class='Modifier'>`</span> <span class='Number'>3</span><span class='Ligature'>‿</span><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>1</span><span class='Ligature'>‿</span><span class='Number'>1</span> + <span class='Paren'>(</span><span class='Function'>-</span><span class='Modifier'>˜˝</span><span class='Function'>≠↕</span><span class='Number'>0</span><span class='Function'>∾⊢</span><span class='Paren'>)</span> <span class='Function'>+</span><span class='Modifier'>`</span> <span class='Number'>3</span><span class='Ligature'>‿</span><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>1</span><span class='Ligature'>‿</span><span class='Number'>1</span> ⟨ 3 2 1 1 ⟩ </pre> <p>This method extends to any number of initial elements.
