What will be the output of the following program:r = lambda q: q * 2s = lambda q: q * 3x = 2x = r(x)x = s(x)x = r(x)print (x)
Question
What will be the output of the following program:
r = lambda q: q * 2
s = lambda q: q * 3
x = 2
x = r(x)
x = s(x)
x = r(x)
print(x)
Solution
The given program is written in Python. Here's a step-by-step explanation of what it does:
-
r = lambda q: q * 2: This line defines a lambda functionrthat takes an argumentqand returnsq * 2. -
s = lambda q: q * 3: This line defines another lambda functionsthat takes an argumentqand returnsq * 3. -
x = 2: This line assigns the value2to the variablex. -
x = r(x): This line calls the functionrwithxas the argument. Sincexis2,r(x)is2 * 2, which is4. So,xis now4. -
x = s(x): This line calls the functionswithxas the argument. Sincexis4,s(x)is4 * 3, which is12. So,xis now12. -
x = r(x): This line calls the functionrwithxas the argument. Sincexis12,r(x)is12 * 2, which is24. So,xis now24. -
print (x): This line prints the value ofx, which is24.
So, the output of the program will be 24.
