Second F2F interview with Morgan Stanley

  1. Introduce yourself.

    1 + 2 – 3                 Answer : 0
    4 / 4 * 4                  Answer : 4
Note :
* and / has equal precedence. 
+ and – has equal precedence.
Assume that * and / has greater precedence over + and -.
if two operators have equal precedence, then operator on the left side should be given a priority.
