How does the execution of dead code waste time?
The execution of dead code wastes computation time and memory. While the result of a dead computation may never be used, it may raise exceptions or affect some global state, thus removal of such code may change the output of the program and introduce unintended bugs.

Dead code is the part of the code which is not get executed while the code is running. Here the code below the return statement is considered as dead code since that code will not get executed at all. That part of code will not have an effect in the code.
How is dead code used in data flow analysis?
Dead code analysis can be performed using live variable analysis, a form of static code analysis and data flow analysis. This is in contrast to unreachable code analysis which is based on control flow analysis. The dead code elimination technique is in the same class of optimizations as unreachable code elimination and redundant code elimination.
