can anyone answer for this ?

Int Test ( int j)
{
j = j-1;                          // this should be  j= j+1 but the programmer accidently has put -1
j = j/30000;
return j;
}


The line j=j-1;  is incorrect in this function.
Function Test accepts an integer j, subtracts one from it, divides it by 30000 (integer division, result is the whole number no remainder) and returns the value just computed.
Integers are implemented by using 16 bits in this computer executing this program/function, as result the lowest possible input value is -32,768 and the highest one is 32,767.
Thus there are 65,356 possible inputs into this program.
Will we create and run all 65,536 test cases to test this program?
If not, which input values we would choose that would be able to detect this bug?

Input (j)
Expected Result
Actual Result

29999 coz we assume te result to be 1 but comes something else...
