a. Recurrence is T(n) = T(n-2) + O(n) and time complexity is O(n^2)
b. Recurrence is T(n) = T(n-1) + O(n) and time complexity is O(n^2)
c. Recurrence is T(n) = 2T(n/2) + O(n) and time complexity is O(nLogn)
d. Recurrence is T(n) = T(n/10) + T(9n/10) + O(n) and time complexity is O(nLogn)
b. Recurrence for Worst Case of Quick Sort is T(n) = T(n-1) + O(n) and
time complexity in Worst Case O(n^2)
