WebTo loop through a 1D array you need a single for-loop, accessing each index once, which is obviously O (n) . To loop through a 2D array, you must use a nested for-loop, but this doesn't mean the time complexity is O (n^2), you are still only accessing each index once, so the time-complexity is O (n). WebYou could create a nested for-loop, and have a counter that you increment each time, until it equals the 13th index. int counter = 0; for (int j = 0; j < y; j++) { for (int i = 0; i < x; i++) { counter++; } } Alternatively, you could make use of the modulus function and divide function.
