Part 3 - Debugging NOTE: Please use the debugger to find out the bugs. Kevin, Samantha and Aditya were developing a program that takes in from the user a sequence of numbers separated by + or . Their program would add the numbers depending on the arithmetic operations entered by the user. Once the sum of the numbers fell below zero, the program prints out "Sum fell below zero." They verify if the character entered is a number or not, and they check if the sign entered is ' + ' or ' ' '. If not, the user is asked to re-enter till a valid input is taken. The numbers and signs are separated by . All numbers and signs are entered as characters. Unfortunately, their code does not work, and they hire you to fix their code. You are given the following code
