The compliment of the Boolean expression Aꞌ • (B • Cꞌ + Bꞌ • C)

Convert the following infix notation to prefix form.
(A–B)/C*(D+E)

Study the given propositions and the statements marked Assertion and Reason that
follow it. Choose the correct option on the basis of your analysis.
p = I am a triangle
q = I am a three-sided polygon
s1 = p → q
s2 = q → p
Assertion: s2 is converse of s1
Reason: Three-sided polygon must be a triangle.

Name the entity described above and state its principle.

According to the Principle of duality, the Boolean equation
(Aꞌ + B) • (1 + B) = Aꞌ + B will be equivalent to:

Given below are two statements marked Assertion and Reason. Read the two
statements carefully and choose the correct option.
Assertion: Recursion utilises more memory as compared to iteration.
Reason: Time complexity of recursion is higher due to the overhead of
maintaining the function call stack.

Given below are two statements marked Assertion and Reason. Read the two
statements carefully and choose the correct option.
Assertion: In Java, the String class is used to create and manipulate strings, and it
is immutable.
Reason : Immutability ensures that once a String object is created, its value cannot
be changed.
