Give a recursive implementation for the function: def is_sorted(lst, low, high) This function is given a list of numbers, lst, a

s well as two indices: low and high (low ≤ high), which indicate the range of the indices for the elements that should to be considered. When called, the function should determine if the elements that are placed at the low, low+1, …, high positions, are in an (ascending) sorted order. That is, it should return True if-and-only-if lst[low] ≤ lst[low+1] ≤ … ≤ lst[high] For example, if lst = [1, 3, 6, 8, 12, 15, 31], the call is_sorted(lst, 0, 6), will return True. Implementation requirements: Your function should run in worst case linear time. That is, if n is the size of the range low, low+1, …, high, calling is_sorted(lst, low, high) will run in �(�). Note: Write your implementation.

Answer:

# recursive method to find if list is in ascending order

def is_sorted(list, low, high):

   if low >= high:     # if reached end of list

       return True

   if list[low] > list[low+1]:     # if item at low is greater than low+1

       return False                # return false

   return True and is_sorted(list, low+1, high)    # or return True and recursion call to low+1

Write a recursive method called lengthOfLongestSubsequence(a, b) that calculates the length of the longest common subsequence (l
kompoz [17]

Answer:

Explanation:

The following code is written in Java and creates the recursive function to find the longest common substring as requested.

 static int lengthOfLongestSubsequence(String X, String Y) {

       int m = X.length();

       int n = Y.length();

       if (m == 0 || n == 0) {

           return 0;

       }

       if (X.charAt(m - 1) == Y.charAt(n - 1)) {

           return 1 + lengthOfLongestSubsequence(X, Y);

       } else {

           return Math.max(lengthOfLongestSubsequence(X, Y),

                   lengthOfLongestSubsequence(X, Y));

       }

   }

What name is given to any changes to the original data such as users manually modifying data, programs processing and changing d
nadezda [96]

Modification is the name given to an attack that makes changes into original data such as users manually modifying data, programs processing and changing data, and equipment failures.

In modification attacks, only changes are made to original data without deleting it completely. Modification is basically a type of attack in the context of information security. This type of attack creates annoying situations and discords by altering existing data in data files, inserting new false information in the network and reconfiguring network topologies and system hardware.

Modification attack is mainly mounted against sensitive and historical data. Modification attacks target integrity of the original data with an intent of fabricating it.
