Calling external contracts

When adding a question for voting, the address of the contract is set, to which the results are transmitted after the completion of voting and the hash of the function (first 4 bytes), which should be called in this contract.

At the end of voting, the specified function of the external contract is called. The call passes a list of the following parameters:

• Question id
• Voting id
• Launch date
• Voting result
• The list of voting parameters in the order in which they are indicated in the question
