PROBLEM 1: SUMMATION The summation symbol \( \sum_{a}^{i} \) is used to sum numbers from \( i \) to \( n \). An example of summation is as follow: \[ \begin{array}{l} 3 \\ \sum_{6} \\ =3+4+5+6 \\ =18 \end{array} \] LAB EXERCISE \( 2.1 \) Estimate Time: 30 Minutes Tasks: Build a complete ITERATIVE program for computing the summation of \( i \) and \( n \). Summation operation must be done in a separate function (not in the main function). LAB EXERCISE \( 2.2 \) Estimate Time: 30 Minutes Tasks: Build a complete RECURSIVE program for computing the summation of \( i \) and \( n \).
