The default lexicographic comparator satisfies all constraints above. Plagium reports display differences in a visual format that is easy to understand and. Explanation: the string 'Frog' in cell A1 and the string 'frog' in cell B1 are not exactly equal to each other (first letter in uppercase and first letter in lowercase). One is case-sensitive and one is case-insensitive. A comparator that always returns 0 will cause the array to not be changed at all, but is reliable nonetheless. File comparison: Plagium can help you to compare text documents. This example shows two ways to compare text strings in Excel. For example, if a comparator only returns 1 and 0, or only returns 0 and -1, it will not be able to sort reliably because symmetry is broken. Transitive: If compareFn(a, b) and compareFn(b, c) are both positive, zero, or negative, then compareFn(a, c) has the same positivity as the previous two.Ī comparator conforming to the constraints above will always be able to return all of 1, 0, and -1, or consistently return 0.Symmetric: compareFn(a, b) and compareFn(b, a) must both be 0 or have opposite signs.

Stable: The comparator returns the same result with the same pair of input.

(This is important because there's no guarantee when and how the comparator will be called, so any particular call should not produce visible effects to the outside.)

Pure: The comparator does not mutate the objects being compared or any external state.More formally, the comparator is expected to have the following properties, in order to ensure proper sort behavior: Deprecated Object.prototype._lookupSetter_().Deprecated Object.prototype._lookupGetter_() Online Text Compare Online HTML Compare This tool lets you compare the differences between two HTML Files.Deprecated Object.prototype._defineSetter_() Text compare is One of the Best with the help of diff checker after comparing text or files and gives you accurate results.Deprecated Object.prototype._defineGetter_().
