    Minor correction In Question 32 at 2:31:30 answer will be Θ(n^2logn),as f(n) & n^logb a will became equal.
    Q42
    T(n)=2T(√n) + (logn)^3
    2^m=n
    T(2^m)=2T(2^m/2) + m^3
    T(2^m)=S(m)
    S(m)=2S(m/2) + m^3
    S(m)=Θ(m^3)
    T(2^m)=Θ(m^3)
    T(n)=Θ((logn)^3)
    Q43
    T(n)=4T(√n) + (logn)^2
    2^m=n
    T(2^m)=4T(2^m/2) + (m)^2
    T(2^m)=S(m)
    S(m)=4S(m/2) + m^2
    S(m)=Θ(m^2.logm)
    T(2^m)=Θ(logn^2.loglogn)
    Q44
    T(n)=12T(n^(1/3)) + (logn)^2
    2^m=n
    T(2^m)=12T(2^(m/3)) + (m)^2
    T(2^m)=S(m)
    S(m)=12S(m/3) + (m)^2
    S(m)=Θ(m^log3 12)
    T(n)=Θ((logn)^log3 12)
