O b) T(n) = 2(n)
O c) T(n) = O(n)
d) T(n)=6n-5 for n > 1
O e) T(n)=2n-1 n > 1

Which of the following recurrence relations are O(n)?
You may assume n is a power of 2.
О a) Т(п) — 2T(n/2) + п, T(1) %3D 1
O b) T(n) = 2T(n/2) + 1, T(1) = 1
О) T(п) — 2T (n/2) + 1, Т(1) —D п
2T(n/2) + 1, T(1) = n
O d) T(n) = T(n – 1) + 1, T(1) = 1
%3D
O e) T(n) = T(n – 1) + n, T(1) = 1
