Let’s debug this a little, add a few system outs…<\/p>\n
this is what you would see for each step
\n100.0 – 5.0
\n95.0 + 10.0
\n105.0 + 13.0
\n118.0<\/p>\n
your value array is {100,5,10,13} and your operator array is {-,+,+}<\/p>\n
you have not mapped a = 100, b = 5, c= 10, d = 13, unless you map those then parse the operands using the mapping based on the non operand input keys, it is not going to work.<\/p>\n
So, if I were to use the character’s int values, I would be able to translate it this way.<\/p>\n
