@Ronnieraj37 could you review the pr and tell if any changes are required
i have yet not not added tests for the updated function , just updated the existing ones , we can add some tests for the updated functions as well

Hey @rairohit17 Pl add a check for _candidates .length >= 2 in the createElection from the solidity side. So that we do not have bots creating empty elections from block explorer.

hey @Ronnieraj37 i have added a check for _candidates.length>2 also i have added a warning for the same in frontend

Apart from that i have updated all tests and made them compatible with the contract's changes
i have also added optimizer for reducing the contract's bytecode size and lower gas costs when deploying as the contracts byecode exceeded the limit
please review and let me know if any changes are required
