C language Determine the Big O running time of the following code fragment with the explanation of calculation. (Follow the way that you see in class, like what is happening in the first step, second step,..., kth step). Consider that you are calling the fun() function by passing an array and its size m.
int fun(int *array, int m)
{
int k = 0, j=0;
for(k=0; k<=m*m; k++)
j = func2(array, m);
}
int func2(int m) {
int i = 0, sum=0;
while (m>0) {
m = m/2;
sum+=array[m-1];
}
return sum;
}

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
