📝 Smart Contract Code

import { Contract, GlobalState, uint64 } from "@algorandfoundation/algorand-typescript"

export class Voting extends Contract {

// Global state variables candidateA = GlobalState({ key: "candidateA", initialValue: 0 }); candidateB = GlobalState({ key: "candidateB", initialValue: 0 });

// Function to vote for Candidate A voteForA(): uint64 { this.candidateA.value = this.candidateA.value + 1; return this.candidateA.value; }

// Function to vote for Candidate B voteForB(): uint64 { this.candidateB.value = this.candidateB.value + 1; return this.candidateB.value; }

// Get current winner getWinner(): string { if (this.candidateA.value > this.candidateB.value) { return "Candidate A"; } else if (this.candidateB.value > this.candidateA.value) { return "Candidate B"; } else { return "Tie"; } } }
