Consider the following program segment in which the statements are jumbled.
Choose the correct order of statements to calculate and return the factorial of 4.
for(k = 1; k <= 4; k++) → 1
return fa; → 2
long fa = 1, k; → 3
fa *= k; → 4
- 1, 2, 3, 4
- 3, 1, 4, 2
- 3, 1, 2, 4
- 1, 3, 2, 4

Answer
3, 1, 4, 2
Reason — To calculate and return the factorial of 4 using a loop, we must follow the proper sequence of statements:
long fa = 1, k;– This is the declaration and initialization of variablesfaandk.for(k = 1; k <= 4; k++)– This sets up a loop to run from 1 to 4.fa *= k;– This multiplies the current value offabykduring each iteration.return fa;– This returns the final calculated factorial value.
So, the correct order is: 3, 1, 4, 2, which correctly calculates and returns the factorial.
