An asynchronous 4-bit binary down counter changes from count 2 to count 3. How many transitional states are required?

An asynchronous 4-bit binary down counter changes from count 2 to count 3. How many transitional states are required? Correct Answer 15

Transitional state is given by (2n – 1). Since, it’s a 4-bit counter, therefore, transition states = 24 – 1 = 15. So, total transitional states are 15.

Consider the following code. int count = 0; void *thfun () { int ctr=0; for (ctr=0; ctr<100; ctr++)      count++; } If thfun is executed by two threads concurrently in a uniprocessor system, what will be the MINIMUM value of count when both threads complete their execution? Assume that count++ is performed using three instructions: (i) read value of count from memory to a CPU register R, (ii) increment R, and (iii) store the value of R in memory. 
Statement (I): The count-up overflow (OV) bit is 1 when the up-counter increments above the maximum positive value. Statement (II): The count-down underflow (UN) bit is 1 when the counter decrements below the minimum negative value.
