given.. t(0) = 3 n <= 1 t(n) = 3t(n/3) + n/3 n > 1 so answer's suppose o(nlogn) .. here's how did , it's not giving me right answer: t(n) = 3t(n/3) + n/3 t(n/3) = 3t(n/3^2) + n/3^2 subbing t(n) gives.. t(n) = 3(3t(n/3^2) + n/3^2) + n/3 t(n/3^2) = 3(3(3t(n/3^3) + n/3^3) + n/3^2) + n/3 eventually it'll like.. t(n) = 3^k (t(n/3^k)) + cn/3^k setting k = lgn.. t(n) = 3^lgn * (t(n/3^lgn)) + cn/3^lgn t(n) = n * t(0) + c t(n) = 3n + c the answer's o(n) though..what wrong steps? t(n) = 3t(n/3) + n/3 t(n/3) = 3t(n/9) + n/9 t(n) = 3(3t(n/9) + n/9) + n/3 = 9t(n/9) + 2*n/3 //statement 1 t(n/9)= 3t(n/27) + n/27 t(n) = 9 (3t(n/27)+n/27) + 2*n/3 // replacing t(n/9) in statement 1 = 27 t (n/27) + 3*(n/3) t(n) = 3^k* t(n/3^k) + k* (n/3) // replace k log n base 3. t(n) = n t(1) + (log n) (n/3); // t(1) = 3 t(n) = 3*n + (log n) (n/3); hence , o (n* logn)

is possible create rewrite code includes wildcard? for example request for: http://example.com/something1/something2/* would redirect to: http://example.com/newthing and will matter in .htaccess file place rewrites? this should work you: rewriteengine on rewriterule ^something1/something2/(.*)$ /$1 [r=302,l] it should change http://example.com/something1/something2/test http://example.com/test edit: rewriteengine on rewriterule ^shirts/(.*)$ /clothing.html [r=301,l]
