Sequence Accumulation
Write n function
T accum(
that forms and returns the “sum” of all items in the vector v passed to it. For example, if T is a numeric type such as int or double, the numeric sum will be returned, and if T represents the STL string type, then the result of concatenation is returned.
NOTE: For any type T, the expression T() yields the value or object created by the default constructor. For example, T() yields the empty string object if T is the string class. If T represents a numeric type such as 1nt, then T() yields 0. Use this fact to initialize your “accumulator.”

- vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 Truearrow_forwardIn C programming language Question (Strings) Write a function find_Substring() that finds a substring into a string. Pass array s1 and s2 to this function and prints if the substring is present or not. Expected Output 1: Enter string This is a javascript Enter substring script The substring is present Expected Output 2: Enter string This is a javascript Enter substring Jscript The substring is not presentarrow_forwardQuestion > Not complete Marked out of 1.50 Flag question Previous page Write a recursive function named get_palindromes (words) that takes a list of words as a parameter. The function should return a list of all the palindromes in the list. The function returns an empty list if there are no palindromes in the list or if the list is empty. For example, if the list is ["racecar", "hello", "noon", "goodbye"], the function should return ["racecar", "noon"]. A palindrome is a word that is spelled the same forwards and backwards. Note: The get_palindromes() function has to be recursive; you are not allowed to use loops to solve this problem. For example: Test words = ["racecar", "hello", "noon", "goodbye", "test", 'aibohphobia'] ['racecar', 'noon', 'aibohphobia'] print (get_palindromes (words)) print (get_palindromes ([])) print (get_palindromes (['this', 'is', 'test'])) Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) Result Precheck Check [] [] Next pagearrow_forward
- mplement a function gct according to these guidelines: The function accepts a single positive integer which represents a number of tablespoons of a liquid. You may assume that this number is always between 0 and 25599 (inclusive of both). The function returns a formatted str containing an equivalent number of gallons, cups andtablespoons. The answer should use as many gallons, then cups as possible. For example:gct(312) would return '01g,03c,08t' as 312 tablespoons is equivalent to 1 gallon, 3 cups, and 8 tablespoons. Each of the output quantities (gallons, cups, tablespoons) should occupy two digits. If the values have less than two digits, they should be padded with leading zeroes. I.e., 2 cups is represented by '02c' .arrow_forwardExercise Objectives Problem Description Write a program that reads a string and mirrors it around the middle character. Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.arrow_forwardC++ Format Please Write a function (named "Lookup") that takes two const references to vectors. The first vector is a vector of strings. This vector is a list of words. The second parameter is a list of ints. Where each int denotes an index in the first vector. The function should return a string formed by concatenated the words (separated by a space) of the first vector in the order denoted by the second vector.

- Treasure Hunter description You are in front of a cave that has treasures. The cave canrepresented in a grid which has rows numbered from 1to , and of the columns numbered from 1 to . For this problem, define (?, )is the tile that is in the -th row and -column.There is a character in each tile, which indicates the type of that tile.Tiles can be floors, walls, or treasures that are sequentially representedwith the characters '.' (period), '#' (hashmark), and '*' (asterisk). You can passfloor and treasure tiles, but can't get past wall tiles.Initially, you are in a tile (??, ). You want to visit all the treasure squares, andtake the treasure. If you visit the treasure chest, then treasurewill be instantly taken, then the tile turns into a floor.In a move, if you are in a tile (?, ), then you can move tosquares immediately above (? 1, ), right (?, + 1), bottom (? + 1, ), and left (?, 1) of thecurrent plot.

- Probelm part 1: Define a function called common_divisors that takes two positive integers m and n as its arguments and returns the list of all common divisors (including 1) of the two integers, unless 1 is the only common divisor. If 1 is the only common divisor, the function should print a statement indicating the two numbers are relatively prime. Otherwise, the function prints the number of common divisors and the list of common divisors. Complete each to do with comments to expalin your process. Problem part 2: complete the following todo's and make comments to explain each step # TODO: Define the function 'common_divisors' with two arguments 'm' and 'n'. # TODO: Start with an empty list and append common divisors to the list. # TODO: Create a conditional statement to print the appropriate statement as indicated above. Problem part 3: Call the function common_divisors by passing 5 and 38. Your output should look like this: 5 and 38 are relatively prime. # TODO: Call…arrow_forwardWhat input or parameter value impacts the number of times the recursive function will be called. • Give three specific examples of input/parameter values and, for each, state the number of times the recursive function will be called. • Devise a formula with respect to n that describes the number of times the recursive function will be called, where n is either the value passed or some property of the value passed (e.g. n might be the length of a string of the size of an array).arrow_forwardCharacter Count Code in C languagearrow_forward
