Function: longestCommonSubsequence() ​

ts
function longestCommonSubsequence<T>(
   array1: ArrayLike<T>, 
   array2: ArrayLike<T>, 
   options: LongestCommonSubsequenceOptions<T>): T[];

Defined in: longest-common-subsequence.ts:46

Determine the longest possible array that is subsequence of both of given arrays.

Type Parameters ​

Type ParameterDescription
TType of objects in the arrays.

Parameters ​

ParameterTypeDescription
array1ArrayLike<T>First array of objects.
array2ArrayLike<T>Second array of objects.
optionsLongestCommonSubsequenceOptions<T>Functions to compare and collect elements from the two arrays

Returns ​

T[]

A list of objects that are common to both arrays such that there is no common subsequence with size greater than the length of the list.

Remarks ​

Implementation of Longest Common Subsequence algorithm.

Example ​

typescript
longestCommonSubsequence(
 ['a', 'b', 'c', ' ', 'd', 'e', 'f'],
 ['a', 'c', ' ', 'd', 'e', 'c'],
); // ['a', 'c', ' ', 'd', 'e']
