+- L144/423/471 - You can save gas if instead of doing uint256() > 0 you do != 0.

+- L180/242/300/348 - When we create a variable and we want it to have its base value, it is not necessary to set that value, since this would imply a double setting.
+
+- L180/300 - When we are using a for and the length of the array is constantly consulted inside, it would be less expensive to create a variable in memory of the length of the array.

+- L180/242/300/348/358 - When a uint256 value is impossible to overflow, such as in a for loop, it can become unchecked.
