If there is no answer, return the empty . PHP Array Exercise: Get the shortest, longest string length from an So from 'qugteroda', I should get rag outed, outraged, out dare, out read, outrage,readout. Write a PHP script to get the shortest/longest string length from an array.

This works by looking at the differences between successive values, which is zero within a run, which means that non-zero values mark the beginning and end of a run (Because you have to account for runs terminating at the beginning and end of the array you are querying, you have to append a 1 to the beginning and end of the difference array, hence the transposition of A in the command line above). Previous: Write a JavaScript to add two positive integers without carry. var strSplit = The quick brown fox jumped over the lazy dog.split( ); var strSplit = [The, quick, brown, fox, jumped, over, the, lazy, dog]; var sortArray = [The, quick, brown, fox, jumped, over, the, lazy, dog].sort(); var sortArray = [The, brown, dog, fox, jumped, lazy, over, quick, the]; [].sort(function(firstElement, secondElement) {.

Never forget APL is evaluated right-to-left: Other than the parentheses, this actually seems pretty good! Would you say that the way I did it was inefficient? The numbers of implanted and recommended electrode arrays of each type are given in Table 1. function findLongestWordLength (str) { const regex = / ( [a-z]+)/gi; const matches = str.match (regex); let last_longest = 0; for (let i = 0; i<matches.length; i++) { if (matches [i].length > last_longest) { last_longest = matches [i].length; } } return last_longest; } Is there any way to find the longest word in a string with an array? your vector of values and look at the output, you might realize that you are back in the frame of the original question (and you would be looking for sequences of zeros). In each iteration of the callback, we return the longer of the two words. @LiefdeWen OrderBy is stable so this will in fact return last element in case of a tie. We will need to add an empty space between the parenthesis of the split() method. If cell has first character, then we one by one try all 8 directions from that cell for a match.
