Implement and display the runtime for each algorithms in problem :

a) int sum = 0;

for (int i = 1; i <= n; i++)

for (int j = 1; j <= n; j+=2)

sum += (i+j);

b) int sum = 0;

for (int i = 1; i <= 50; i+=2)

for (int j = 1; j <= n; j+=3)

sum += (i+j);

c) int sum = 0;

for (int i = 1; i <= m; i++)

for (int j = 1; j <= n; j*=2)

sum += (i+j);

d) int sum1 = 0;

for (int i = 1; i <= m*m; i++)

sum1 += i;

int sum2 = 0;

for (int j = 1; j <= m; j++)

sum2 += j;
