What is the time complexity T(n) of the following program?
a)
int n, d, i, j;
cin >> n;
for (d=1; d<=n; d++)
for (i=1; i<=d; i++)
for (j=1; j<=n; j += n/10)
cout << d << " " << i << " " << j << endl;
b)
void main()
{ int n, s, t;
cin >> n;
for (s = 1; s <= n/4; s++)
{t = s;
while (t >= 1)
{ cout << s << " " << t << endl;
t--;
}
}
}
c)
void main()
{ int n, r, s, t;
cin >> n;
for (r = 2; r <= n; r = r * 2)
for (s = 1; s <= n/4; s++)
{
t = s;
while (t >= 1)
{
cout << s << " " << t << endl;
t--;
}
}
}
