It prints the following

$\\ b_1,b_1,b_1\\ b_1,b_1,b_2\\ b_1,b_1,b_3\\ ..........\\ ..........\\ b_n,b_n,b_n\\$

This algorithm prints out all the possible ways to draw 3 balls with replacement.(because for first output

$\\ b_1,b_1,b_1\\$ itself shows that ball $\\ b_1$ was replaced and drawn again)

Since there are 3 for loops and each loop iterates n times, the number of lines it prints =  $n^3$
