# Challenge 3: Find the Highest Achiever

Given multiple subject files find the student who has the maximum total marks.

## We'll cover the following

## Problem Statement

Implement a function `findTopper()`

that takes input from three subject files: `math.csv`

, `english.csv`

and `science.csv`

, and find the index of the student that has scored the maximum total marks adding all three of its marks.

### Input

Three files: `math.csv`

, `english.csv`

and `science.csv`

### Output

Index of the highest scoring student

### Sample Input

`math.csv`

```
Name, Math
Andrew, 2.5
Mathew, 5.9
Dany, 1.9
Philip, 9.1
```

`english.csv`

```
Name, English
Andrew, 8.2
Mathew, 2.5
Dany, 7.5
Philip, 9.3
```

`science.csv`

```
Name, Science
Andrew, 5.2
Mathew, 9.5
Dany, 7.1
Philip, 1.9
```

### Sample Output

```
4
```

### Test Yourself

Write your code in the given area. If you get stuck, you can look at the solution.

main.r

math.csv

english.csv

science.csv

findTopper <- function(){# Write your code here}

In the next lesson, we give a brief overview of the solution to this problem.
