I'm currently working on a project that involves combining elements from a multidimensional array to create different combinations.
For example, if I have the following array:
var array = [
['a'],
['1', '2', '3', '4'],
['A']
];
The desired output would be:
["a1A", "a2A", "a3A", "a4A"]
To achieve this result, I have implemented the following code:
var finalArray = [];
var f1 = 0;
for (var i = 0; i < array.length - 1; i ++) {
f1 = 0;
for (var j = 0; j < array[i].length; j ++) {
for (var k = 0; k < array[i + 1].length; k ++) {
if (finalArray[f1])
finalArray[f1] += array[i + 1][k];
else
finalArray[f1] = array[i][j] + array[i + 1][k];
f1 ++;
}
}
}
console.log(finalArray);
The issue arises when additional elements are added to the first or last member of the array, as the code does not produce the expected output.
For instance, consider the following array:
var array = [
['a', 'b'],
['1', '2', '3', '4'],
['A']
];
Instead of getting:
["a1A", "a2A", "a3A", "a4A", "b1A", "b2A", "b3A", "b4A"]
The code currently returns:
["a1A", "a2A", "a3A", "a4A", "b1", "b2", "b3", "b4"]
If anyone has suggestions on how to improve this code to handle additional elements correctly, please let me know. Your help is greatly appreciated.
