a. n, one for loop
b. n^2, nested for loop
c. log(n), as x is doubling every loop
d. n^2, one for loop
e. n

a.
b.
c.
d. n log(n), as j is doubling every loop
e.

a. log(n), reducing each loop amount
b.
c.
d. n^3, as inner for loop runs n*n
e. n^2, worst case scenario with nested for loops
f. n^3, three loops running n times each
g. n^2, nested for loop
h. n times, as the n function is slower than logarithm
i. n^4, as the nested loop is defined by i = n*n
