CS 150: Problem Solving and Programming I Programming Exercise #4 The while loop in the following program is supposed to read some numbers until it reaches a sentinel (in this case, -1). It is supposed to add all the numbers except for the sentinel. If the data looks like: 12 5 30 3-1 the program does not add the numbers correctly. Correct the program so that it adds the numbers correctly.
