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--;
}
}
}

Write a program using two-dimensional arrays that determines the highest and lowest of the 12 input values. Example: Enter 12 numbers: 13 15 20 13 35 40 16 18 20 18 20 14 highest: 40 lowest: 13
Write a (n) algorithm that sorts n distinct integers, ranging in size between 1 and kn inclusive, where k is a constant positive integer. (Hint: Use a kn-element array.)
write a c program, using for loop, that accepts and odds two numbers. The output must be the sum and the addens. This should be repeated 5 times while the first number is decremented by one and the second number is incremented by 1.
main(){int a=5,b 10,c=2, d;a=b c;d=++a=(--c)*2; printf("%d%d%d%d,a,b,c,d; return o;}

Algorithm in O(2n) Presently we can solve in our hypothetical machine problem instances of size 100 in 1 minute using algorithm A, which is a O(2n). We would like to solve instances of size 200 in 1 minute using algorithm A on a new machine. What is the speed of the new machine should be?
