Explanation:
Detailed explanation-1: -So to achieve 100% decision coverage we will need minimum 5 test cases.
Detailed explanation-2: -4 test cases are required for 100% decision coverage.
Detailed explanation-3: -For a test set to achieve 100% branch coverage, every branching point in the code must have been taken in each direction, at least once. The archetypical example, showing that 100% statement coverage does not imply 100% branch coverage, was already given by Alexey Frunze.
