Severity:
use unchecked {++i;} for loops to save gas
Summary
use unchecked {++i;} for loops to save gas
Vulnerability Details
As the iterator is bound by the length of the array, the iterator would never overflow. So, the following can be done to save gas in for loops:
unchecked {
++i;
}
Impact
Saves gas on various iterations, as the compiler need not check for overflow on each increment operation of the iterator.

Recommendations
