(HackerRank) Write a Modular C Programming code to solve 2D ARRAYS- Election of Candidates, An election is contested by 5 candidates. The candidates are numbered 1 to 5
An election is contested by 5 candidates. The candidates are numbered 1 to 5 and the voting is done by marking the candidates number on the ballot paper. Apply Problem solving framework and Write a modular C program to read the ballots and count the vote cast for each candidate.
Input Format
First line indicates number of Candidates.
Second line indicates number of voters.
Further lines indicate matrix of votes casted by voters.
Constraints
Vote can be either 0 or 1 by a voter.
1 indicates a voter casted a vote to one candidate only. For other candidates vote becomes 0.
Output Format
Display candidate wise vote count.
Sample Input 0
5 4
1 1 0 0
0 0 0 0
0 0 1 0
0 0 0 0
0 0 0 1
Sample Output 0
Candidate 1: 2
Candidate 2: 0
Candidate 3: 1
Candidate 4: 0
Candidate 5: 1
Sample Input 1
2 5
0 1 2 3 4
1 2 3 4 0
Sample Output 1
Invalid votes
Sample Input 2
0 -5
Sample Output 2
Invalid input

if(vote[i][j]!=0 && vote[i][j]!=1)
{
printf("Invalid votes");
exit(0);
}
vote_sum[i]+=vote[i][j];
