4. Consider the function IndexEqual(A,i.j) that returns true if there exists an index x (i sx sj) such that A[x] = x; otherwise, retums false. You may assume A is a sorted integer array in which every element is unique. a. Write an efficient recursive algorithm for IndexEqual(A,i.j). b. What is the situation resulting in the best-case running time of your function, and give an expression for that running time? c. What is the situation resulting in the worst-case running time of your function, and give an expression for that running time in terms of n, where n=j-i+1?

In C++: Given the following recursive definition seq(1) = seq(2) = 1 seq(n) = 2*seq(n-1) + 3*seq(n-2) implement the corresponding program and use it to calculate seq(5). How many invocations are made to the function seq when calculating seq(5)?
2. The function f is defined for non-negative integers a and b recursively as follows: f (а, b) 3D1 if a = 0 or b = 0 f (a - 1, b f (a f (а, а) 1) + 2a - 1 if a if a > b if a < b b b, b) + f (b, b) + f (b а, а) } Compute f (2, 3) by drawing a recursion tree showing all of the computation required and then use your tree to compute the answer.
I need help with this pratice run question. In C++, Implement a Hash Table of size 8191 (= 2^13 - 1) to store integers based on quadratic probing. Design your own hash function that is, in your view, sufficiently non-trivial and efficient to compute. Compare the average number of probes for the following cases:Generate 4000 integer random numbers in the range 0 to 10^6 - 1, and insert them into the hash table. Compute and print the total number of probes.Repeat step (a) above 10 times, and find the average number of probes over these 10 trials
Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result. - If mystr has at least one instance of adjacent characters being equal, return True - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error") if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie") if not (has_adjacent_repeats("Hanoverr") is True): print("error")

Please send me the answer within 10 min!! i will rate you good for sure!! Please solve all 3 parts in Java with explanation!! Algorithm A: long sum = 0; for (long i = 1; i <= n; i++) sum = sum + i; Algorithm B: sum = 0; for (long i = 1; i <= n; i++) { for (long j = 1; j <= i; j++) sum = sum + 1; } // end for Algorithm C: sum = n * (n + 1) / 2; implement the above three algorithms: There you have the algorithm A, B and C. You will run the three implementations of the algorithms with inputs and do the computation but it does not need to print to the screen the actual sum (for the last value it could exceed the maximum value stored into a long); it should print on the screen the time taken for the running of the algorithm : 1,000,000 1,000,000,000 1,000,000,000,000,000,000 To print the time you should use something like long startTime = System.currentTimeMillis(); methodA(1000000); long endTime = System.currentTimeMillis(); System.out.println("That method…

Write a C function strEven() that takes two strings (say s1, s2) as parameters, stores into s2 the even indexed (0th, 2nd, 4th, ...) characters of s1. s2 must be null character terminated. Example: if s1 is "Abcde1234", the function will make s2 as "Ace24" Prototype: void strEven(char s1[], char s2[]);
