Assignment Content Given two strings s and t, determine if they are isomorphic. Two strings s and t are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character, but a character may map to itself. Example 1: Input: s="egg", t = "add" Output: true Example 2: Input: s="foo", t = "bar" Output: false Example 3: Input: s= "paper", t = "title" Output: true

Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

Question

Assignment Content
Given two strings s and t, determine if they are
isomorphic.
Two strings s and t are isomorphic if the characters
in s can be replaced to get t.
All occurrences of a character must be replaced with
another character while preserving the order of
characters. No two characters may map to the same
character, but a character may map to itself.
Example 1:
Input: s="egg", t = "add"
Output: true
Example 2:
Input: s="foo", t = "bar"
Output: false
Example 3:
Input: s= "paper", t = "title"
Output: true

C++ Code Only: There are two A, B players playing the game. Player A has a string on him, and Player B has a string on him. Both s and t consist of only small English letters and are of equal length. A makes the first move, then B, then A, and so on. Before the start of the game, players know the contents of both the s and t strings. These players form one rope during the game. Initially, the character unit w is empty. In each move, the player removes any single letter from the alphabetical order in sequence and adds this letter anywhere (anywhere) to the letter unit (Note that uw is a unit of characters all the time, and you can insert letters or at the end. It is not an empty list where you can add character in any reference. Please refer to the Definitions for further specifications). If in any stage of the game, the character unit w is more than 1 length and is a palindrome, the player who made the last move wins. If even after the game is over (i.e., when both s and t have turned…

You can assume that the two input strings contain only letters and spaces. Sample calls should look like this: >>> are_anagrams ("bimmy is my friend", "My Bird Fey Minims") True >>> are_anagrams ("bimmy is my friend", "hello everyone") False >>> are_anagrams ("internet anagram server", "I rearrangement servant") True >>> are_anagrams ("internet anagram server", "internet anagram server") True 3. find_movies_by_director 4:11 PM This function takes a list of tuples (representing movies) and a string (representing a name of a director) and returns a 65°F Sunny 11/2/2021 e search
Write a function findLetter based on the following rules: It takes a string named str and a character named ch as parameter, returns the index of the first occurrence of the character ch if the str string contains the character ch; If the relevant character is not found in the string, write a function that returns -1. Call the function inside the main function and test it. You should use the prototype given below: int findLetter (char str [], char ch)

palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage: >>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar'] >>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!") ['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are wow!")==['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] True
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 True
Problem: Substring Pattern Matching Input: A text string t and a pattern string p Output: Does t contain the pattern p as a substring, and if so, where? For example: with t= abaababbaba, p = abba, your function should return 5. int findmatch(char *p, char *t) { int plen = strlen(p); // len of string int tlen = strlen(t); // len of string t //TODO: your code } Analyze your algorithm: what is the big O?
Finding mistakes.This is a program that performs a function to count the number of distinct character types in a character string. With the function name unique_letter, the argument is sentence with the data type as string, the return value is the number of distinct character types in the character string sentence.
Create a function which counts how many lone 1s appear in a given number. Lone means the number doesn't appear twice or more in a row. Examples countLoneOnes (101) → 2 countLoneOnes (1191) → 1 countLoneOnes (1111) → 0 count LoneOnes (462) 0
function [P, A] = rect(L, W) P= 2 (L+ W); A =L*W; end Above function is defined to find perimeter and area of a rectangle. If a rectangle has length 10 mm and width 7 mm then the correct way to get perimeter and area of a given rectangle by executing this function is Select one: a. [A, B] = rect(10, 7) b. rect(7, 10) c. [A, B] = rect(7, 10) d. rect(10, 7)
4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.
