In the code fragment below, start and end are integer values and gcd(x,y) is afunction that computes the greatest common divisor of x and y. I := 0; j := 0; k := 0; for (m := start; m <= end; m := m+1){ if (gcd(m,9381) > 2){ I := I + m; k := k + m; }else{ j := j + m; k := k + m; } } At the end of the loop which of the following expresses a valid relation between I, j and k?

K < i+j

K = i+j

K > i+j

Depends on the values of start and end

How many times is the comparison I >= n performed in the following program?int I = 200, n = 110;main(){ while (i >= n){ I = i-1; n = n+1; }}

An algorithm has two phases. The first phase, initialization, takes time O(n2 log n). The second phase, which is the main computation, takes time O(n3). What is the most accurate description of the complexity of the overall algorithm?

O(n2 log n)

O(n3 log n)

O(n3)

O(n3 + log n)

An airline serves 200 cities and runs 1100 direct flights each day between these cities.Which of the following is a good data structure to represent the collection of flights?

A 200 × 200 array A, where A[i][j] = 1 if there is a direct flight from city I to city j and 0 otherwise.

A stack containing values (i, j) for each pair of cities I, j for which there is a direct flight from city ito city j

A queue containing values (i,j) for each pair of cities I, j for which there is a direct flight from cityi to city j.

A list containing values (i, j) for each pair of cities I, j for which there is a direct flight from city I to city j
