if the given expression is itself in that form and asked to program on it then how to convert it
if i convert it using algebra i am getting different answers compared to the manual answers so

plz check this is a different case in 1st case only decrement operators were used in this case both decrement as well as increment operators are used

please tell me for this expresion :
a = (b++) + (- - b) + (b - -) + b
here b = 4
tell me manually ans : i am getting 15
