The body of the k -loop runs in time O (1). For each i, j the k -loop executes n times therefore it runs in time O ( n · 1), that is O ( n ). Therefore the body of the j -loop runs in time O ( n ). The j -loop executes 3 i times so it runs in time O ((3 i ) n ), However, we always have i < 10 therefore the j -loop executes in time O (30 n ) therefore in O ( n ). So the body of the i -loop runs in time O ( n ) and it executes 10 times so the i -loop (and therefor the entire method) runs in time O (10 n ) that is O ( n ). What happens if we replace 3 with arr.length ? 3

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
