When a function with a memory array is called externally, the abi.decode() step has to use a for-loop to copy each index of the calldata to the memory index. Each iteration of this for-loop costs at least 60 gas (i.e. 60 * <mem_array>.length). Using calldata directly, obliviates the need for such a loop in the contract code and runtime execution. Note that even if an interface defines a function as having memory arguments, it’s still valid for implementation contracs to use calldata arguments instead.
If the array is passed to an internal function which passes the array to another internal function where the array is modified and therefore memory is used in the external call, it’s still more gass-efficient to use calldata when the external function uses modifiers, since the modifiers may prevent the internal functions from being called. Structs have the same overhead as an array of length one
Note that I’ve also flagged instances where the function is public but can be marked as external since it’s not called by the contract, and cases where a constructor is involved

Given 4 variables a, b, c and d represented as such:
0 0 0 0 0 1 1 0 <- a
0 1 1 0 0 1 1 0 <- b
0 0 0 0 0 0 0 0 <- c
1 1 1 1 1 1 1 1 <- d
To have a == b means that every 0 and 1 match on both variables. Meaning that a XOR (operator ^) would evaluate to 0 ((a ^ b) == 0), as it excludes by definition any equalities.Now, if a != b, this means that there’s at least somewhere a 1 and a 0 not matching between a and b, making (a ^ b) != 0.Both formulas are logically equivalent and using the XOR bitwise operator costs actually the same amount of gas.However, it is much cheaper to use the bitwise OR operator (|) than comparing the truthy or falsy values.These are logically equivalent too, as the OR bitwise operator (|) would result in a 1 somewhere if any value is not 0 between the XOR (^) statements, meaning if any XOR (^) statement verifies that its arguments are different.

Counting down is more gas efficient than counting up because neither we are making zero variable to non-zero variable and also we will get gas refund in the last transaction when making non-zero to zero variable.
