Determine the efficiency and big-O notation for the following algorithm:
Anon25 [30]

Answer and Explanation:

To calculate Big O, go through each line of code and determine O(!), O(n) and return your calculation.

For example,

In O (5 +6n), where 6 5 represent five instances of O(1), and 6 represent the 6 O(n).

We compute the time complexity of the algorithm. We get the result, just an estimation. In given algorithms, run time in milliseconds has been provided, such as in T (1) algorithm process in 512 milliseconds and T(2) algorithms process 8129 milliseconds. But big O notation not measured in milliseconds. Information given is not enough to calculate the big O notation.

Reversing the elements of an array involves swapping the corresponding elements of the array: the first with the last, the secon
Alja [10]

Answer:

// Assume that all variables a, n, temp have been declared.

 // Where a is the array, n is the array length, temp is a temporary

 // storage location.

 // Cycle through the array a.

 // By the time the loop gets halfway,

 // The array would have been reversed.

 // The loop needs not get to the end of the array.

 // Hence, the loop ends halfway into the array i.e n/2.

 for (int k = 0; k < n / 2; k++) {

   

  // Swap first and last, second and next-to-the-last and so on

  temp = a[k];

  a[k] = a[n - k - 1];

  a[n - k - 1] = temp;

 }

Explanation:

Explanation has been given in the code in form of comments. Please go through the comments in the code carefully.

Hope this helps!
