Use indexed for loop instead of for each loop to reduce time complexity.
Indexed for loop has a constant time complexity of O(1) whereas for each loop has a time complexity of O(n).
Indexed for loop is faster when accessing elements in an array.
Example: for (int i = 0; i < array.length; i++) { //access array[i] }
Example: for (String str : stringArray) { //access str }
