\<VAR>++ OR \<VAR> += 1 TO ++\<VAR> ALSO USE UNCHECKED FOR OPERATIONS NOT EXPECTED TO OVERFLOW

When the value of the post-loop increment/decrement is not stored or used in any calculations, the prefix increment/decrement operators (++i/--i) cost less gas PER LOOP than the postfix increment/decrement operators (i++/i--)

Use ++i rather than i++ to save gas

Instances include

i++ to ++i:

• zeroswap/contracts/SushiMakerKashi.sol: L97
• zeroswap/contracts/bentobox/BentoBoxV1.sol: L625, L954, L1009, L1018

• zeroswap/contracts/uniswapv2/UniswapV2Router02.sol: L214, L323
• zeroswap/contracts/uniswapv2/libraries/UniswapV2Library.sol: L68, L79

Also add unchecked:

Save gas avoiding initialize variables with 0

MasterChef.sol#L75 This will save you gas
