Implement function rotate that takes a string argument s and an integer argument n, and rotates the string s to the left by n times. For example, the code char s[] = "systems"; rotate(s, 3); will change s into "temssys", while the code char t[] = "abcd"; rotate(t, 1); will change t into "bcda". Restrictions: printf and strlen are the ONLY C library functions that you can use in the implementation. void rotate(char *w, int j)

Implement a function (Java or pseudocode) that will accept a mathematical expression which containssquare brackets, curly brackets and normal brackets (i.e. “[ …]”, “{ …}” and “( … )”) as the input andwould return whether the expression has matching brackets or not. The input expression will be given asa String array where each element in the array is a bracket (one of “[”, “]”, “{”, “}”, “(”, “)”) number ora mathematical operator. It should return true if expression has matching brackets and false otherwise
Implement the following function in C programming language that get a string, and compute an array of non-empty tokens of the string containing only lower-case letters. For example: ● For a string "abc EFaG hi", the list of tokens with only lower-case letters is ["abc", "hi"]. ● For a string "ab 12 ef hi ", the list of such tokens is ["ab","ef","hi"]. ● For a string "abc 12EFG hi ", the list of such tokens is ["ab","hi"]. ● For a string " abc ", the list of such tokens is ["abc"]. ● For a string "+*abc!! B" the list of such tokens is empty.That is, we break the string using the spaces as delimiters (ascii value 32), and look only at the tokens with lower-case letters only . The function get_tokens gets a string str, and returns the array with the tokens containing only lower-case letters in the correct order. The length of the array should be the number of tokens, computed in count_tokens. char** get_tokens(const char* str); For example:● get_tokens("abcEFaG…

Implement a function findMixedCase in Python that: accepts a single argument, a list of words, and returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and returns -1 if the all words are either upper or lower case. sample: >> findMixedCase( ['Hello','how','are','you'] ) # 'Hello' is mixed case0
solve in C please. Implement the following two functions that get a string, and compute an array of non-emptytokens of the string containing only lower-case letters.

Implement regular expression matching with support for '.' and '*'. '.' Matches any single character.'*' Matches zero or more of the preceding element. The matching should cover the entire input string (not partial).

Implement the vacuum cleaning agent function in Python/Java for the scenario described below: Consider two-dimensional Boolean array of size m x n (m and n can each be equal to 4) where m is the number of rows, and n is the number of columns. Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly. If…
Implement the sieve of Eratosthenes: a function for computing prime numbers, known to the ancient Greeks. Choose an integer n. This function will compute all prime numbers up to, and including, n. First insert all numbers from 1 to n into a set. Then erase all multiples of 2 (except 2); that is, 4, 6, 8, 10, 12, ... . Erase all multiples of 3, that is, 6, 9, 12, 15, ... . Go up to ?⎯⎯√n. The remaining numbers are all primes. Make sure that you use functions in your solution, including a main function. Define def sieveOfEratosthenes(n) that receives the maximum value and returns a list of all prime numbers less than or equal to this value in main() print the list of prime numbers.
Write a function/ program that produces the following: int findDifference(const string a1[], int n1, const string a2[], int n2); Return the position of the first corresponding elements of a1 and a2 that are not equal. n1 is the number of interesting elements in a1, and n2 is the number of interesting elements in a2. If the arrays are equal up to the point where one or both runs out, return the smaller of n1 and n2. Notwithstanding each function's behavior described below, all functions that return an int must return −1 if they are passed any bad arguments (e.g. a negative array size, or a position that would require looking at the contents of an element past the last element we're interested in). Unless otherwise noted, passing 0 to the function as the array size is not itself an error; it merely indicates the function should examine no elements of the array. Here's an example: string cast[5] = { "samwell", "jon", "margaery", "daenerys", "tyrion" }; string roles[4] = { "samwell",…
