If you have an if/else if/else code sequence with 4 blocks, what is the minimal number of input values that you should use to test your code?

4 is the correct answer for the above question.

Explanation:

If the if-else sequence has 4 blocks then it will be designed like if, else-if, else-if and then else which made 4 blocks which are as follows:-The first block is an if block.Then the second block is an else-if block.The third block is also else-if block andThe fourth block else blocks.So there is a need of 4 value (one value for each case) to test the application which is defined in the above scenario.It is because when the first if statement is false then the first else-if statement is executed and when the first else statement is false then the second else-if statement is executed and when it is false then the else statement will executed.

Is this a statement or question?
