Give a recursive algorithm that takes as input a string s, removes the blank characters and reverses the string. For example, on input "Hello There", the algorithm should return "erehTolleH". The function IsBlank(c) returns a boolean value indicating whether the character c is the blank character. Your algorithm should not use a loop.

By Heron's formula, the area of atriangle with side lengths a, b, and c is √ s ( s−a )( s−b)( s−c ) , where s=(a+b+ c )/ 2 .>>> triangleArea(2,2,2)1.73205080756887726.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one.

- 12. Consider the recursive function int gcd( int a, int b) int gcd( int a, int b){ if (b > a) return gcd(b,a); if ( b == 0 ) return a; return gcd( b, a% b); } How many invocation (calls) of the gcd() function will be made by the call gcd(72, 30)?c++ Implement a function that recursively calculates the nth number in the Fibonacci sequence of numbers. The Fibonacci sequence starts at 0 and 1. Each number thereafter is the sum of the two preceding numbers. This gives us the following first ten numbers: 0,1,1,3,5,8,13,21,34, .... Input Expected output0 01 17 139 34Part I Implement the Fibonnaci SequenceOne of this week’s quiz questions referred to the Fibonnaci sequence. This sequence of numbers is definedsuch that the nth number of the sequence is simply the sum of the two previous numbers in the sequence. Informal terms, Fn = Fn1 + Fn2, where Fnis the nth Fibonnaci number. Write a function in recursion.py, calledfibonnaci, which will accept one integer parameter (lets call it n) and returns the nth element of the Fibonnacisequence.Part II Implement Euclid’s GCD AlgorithmThe greatest common divisor, or GCD, of two integers is the largest number that divides both of them withno remainder. Euclid’s algorithm is one method to find the GCD of two numbers. Mathematically, we knowthat if r is the remainder when a is divided by b, then gcd(a, b) = gcd(b, r). Write a recursive function calledgcd that takes parameters a and b and returns their greatest common divisor. Think about what the basecase is for this algorithm.Part III String…
- iv) Write a JAVA program to merge two sorted arrays into a single sorted array. Take the sample arrays given below and print the result in the output. The time complexity of the program should be O(N+M) where N and M are the sizes of both the arrays. int []arr1 = {1, 6, 10, 14} int []arr2 = {2, 4, 5, 11, 16, 19} Print the merged array in the output.5.18 C++ Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Ex: If the input is: 5 2 4 6 8 10 the output is: 10,8,6,4,2,please code in python Write a recursive function reverse(sentence) for reversing a sentence. For example, reverse('Who let the dogs out?') will return '?tuo sgod eht tel ohW'. The idea is to remove the first or last letter, reverse the shortened sentence, and then combine the two parts.
- Write a Python function def isSubArray(A,B) which takes two arrays and returns True if the first array is a (contiguous) subarray of the second array, otherwise it returns False. You may solve this problem using recursion or iteration or a mixture of recursion and iteration. For an array to be a subarray of another, it must occur entirely within the other one without other elements in between. For example: [31,7,25] is a subarray of [10,20,26,31,7,25,40,9] [26,31,25,40] is not a subarray of [10,20,26,31,7,25,40,9] A good way of solving this problem is to make use of an auxiliary function that takes two arrays and returns True if the contents of the first array occur at the front of the second array, otherwise it returns False. Then, A is a subarray of B if it occurs at the front of B, or at the front of B[1:], or at the front of B[2:], etc. Note you should not use A == B for arrays.TROUBLESHOOT my PYTHON code, please :) The code of a sequential search function is shown on textbook page 60. In fact, if the list is already sorted, the search can halt when the target is less than a given element in the list. For example, given my_list = [2, 5, 7, 9, 14, 27], if the search target is 6, the search can halt when it reaches 7 because it is impossible for 6 to exist after 7. Define a function linearSearchSorted, which is used to search a sorted list. This function displays the position of the target item if found, or 'Target not found' otherwise. It also displays the elements it has visited. To test your function, search for these targets in the list [2, 5, 7, 9, 14, 27]: 2, 6, 14, 27 and 28. Expected output: List: [2, 5, 7, 9, 14, 27] Search target: 2 Elements visited: 2 Target found at position 0 Search target: 6 Elements visited: 2 5 7 Target not found Search target: 14 Elements visited: 2 5 7 9 14 Target found at position 4 Search target: 27 Elements visited: 2…PYTHON: create a function code(n) that sorts a list of words alphabetically using a RECURSIVE function. tip: a. check if the length of n = 1, if true, return n and stop b. else, if the length of n >= 1, do the ff: c. get the min(x) (least rank word in alphabetical order) d. create a new array from n, where the min is removed. The new array is m. e. return the array composed of the min + code(m).
