**ReNFT** is a multi-chain highly gas-optimised NFT rental protocol and platform that can be whitelabel integrated into any project to enable collateral-free in-house renting, lending, and reward share (scholarship automation).

/**
 * Our contracts take arrays of NFT addresses, their token ids, and other
 * relevant informatino for lending / renting. Contract assumes a specific
 * ordering for these. That is how we achieve minimal gas usage. This function
 * facilitates that ordering. In a nutshell, it puts all the ERC721s together,
 * followed by ERC1155s, which also sit next to each other in the sorted array.
 * This helps our contracts with calling the ERC1155's bundle transfer, and
 * that is yet another gas saving trick.
 *
 * To spend as little gas as possible, arguments must follow a particular format
 * when passed to the contract. This function prepares whatever inputs you want
 * to send, and returns the inputs in an optimal format.
 *
 * This algorithm's time complexity is pretty awful. But, it will never run on
 * large arrays, so it doesn't really matter.
 * @param args arguments that the client is intending to call the contracts
 * with.
