The Greedy Paradigm
Construct a solution iteratively, via a sequence of myopic decisions, and hope that everything works out in the end.
Features and Bugs of the Greedy Paradigm
- Easy to come up with one or more greedy algorithms
- Easy to analyze the running time
- Hard to establish correctness
Warning…
XOR is a logical bitwise operator that returns 0 (false) if both bits are the same and returns 1 (true) otherwise. In other words, it only returns 1 if exactly one bit is set to 1 out of the two bits in comparison.
