Merging two arrays is a common task in programming that involves combining the elements of two separate arrays into a single array. In Java, there are various methods to achieve this, each with its own advantages. In this article, we will explore different techniques to merge two arrays, comp...
-- initialize two arrays t1 = {1,2} t2 = {3,4} -- concatenate the tables function tableConcat(t1,t2) -- loop over t2 items for i=1,#t2 do -- append entries to t1 t1[#t1+1] = t2[i] end -- return merged table return t1 end -- call the function to concatenate arrays t...

. By using thi approach two collection of maps are merged into one collection. Example: // main.dart void main() { Map<String, int> map1 = {'a': 1, 'b': 2}; Map<String, int> map2 = {'c': 3, 'd': 4, 'c': 5}; Map<String, int> mergedMap = {...map1, ...map...

It all goes so well until you get the message that arrays of arrays are not supported. Why? Why have two dimensions on the sheet at all if you are not allowed arrays of arrays; here one row for each distinct number?
Two element arrays change[0 . . . 1], Avalid[0 . . . 1], Bvalid[0 . . . 1] are initialized to 0. The parameter change marks when either of the indices into the input arrays has changed. For this example, change[0] corresponds to array A while change[1] corresponds to array ...
