There are 7 candidates in an election. Each voter is allowed one vote for the candidate of his /her choice. The vote is recorded as a number from 1-7 for each candidate respectively. There are 365 voters in all. Any vote which is not a number 1-7 is invalid and counted as a spoilt vote. You have been commissioned to write a program to automate the computation of the winner of the election.

Write pseudocode for the instant-runoff problem, assuming that the inputs are (1) all the completed ballots, and (2) all the candidates in the election. You may include additional inputs if it helps your algorithm.
