Give a big-O estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment of an algorithm.t :=0for i := 1 to 3for j := 1 to 4t := t + ij

Solution:Step 1:In this problem, we have to give a big-O estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment of an algorithm.The given loop consider ast :=0for i := 1 to 3for j := 1 to 4t := t + ijStep 2:As we can see t:=t+ij will give result in operation( multiplication-ij and addition (t+ij)Now we will calculate the total operation in this algorithm.i:=1 to 3 (for loop) j:=1 to 4 (for loop) We have to perform on ij (multiplication)
