### MATLAB Code Problem

A MATLAB code to compute **sum of cube-of-each-element** of a vector \( v \) is given by:

```matlab
s=0; v=[10 5 8];
for i=1:length(v);
    s=s - v(i^2)*v(i);
end;
s=(s)^(1/3);
```

**(a)** This code, however, has a bug. Fix the bug and write the correct code.

**(b)** What is the value **sum of cube-of-each-element** of the vector \( v \)?

#### Input Box
- __Submit Button__ for executing the code.
- __Attempts Counter__ indicating the number of attempts made for solving the problem. Currently, it shows 1 attempt.

### Explanation
The script intends to compute the sum of cubes of each element of the vector `v`. However, there is a mistake in the code:
- The line `s=s - v(i^2)*v(i);` should be corrected to compute the cubing operation correctly. Instead of subtracting, it should add the cubes of `v` elements.
- Correct expression inside the loop should be `s = s + v(i)^3;`.

The final result should replace the cube root operation (`s=(s)^(1/3);`) to properly align with the intended problem of computing the sum of cubes, not any roots.
