For a better understanding of the problem, check the explanation. Input Format A single line of input consisting of the string . Output Format A single line of output consisting of the modified string. Constraints All the characters of denote integers between and . Sample Input 1222311 Sample Output (1, 1) (3, 2) (1, 3) (2, 1) Explanation First, the character occurs only once. It is replaced by . Then the character occurs three times, and it is replaced by and so on. Also, note the single space within each compression and between the compressions

Refine the is_palindrome function to work with arbitrary strings, by ignoring non-letter characters and the distinction between upper- and lowercase letters. For example, if the input string is "Madam, I’m Adam!" then you’d first strip off the last character because it isn’t a letter, and recursively check whether the shorter string "Madam, I’m Adam" is a palindrome. c++
Write a Matlab function that will: read in the spreadsheet file, accept two textual/string arguments: first metric abbreviation/acronym (for example GP) from the list above, Second metric abbreviation/acronym (for example 3P%) from the list above, finds the player (A) who has the highest/maximum value of the FIRST METRIC (if there is more than one with that value, pick the first one - lowest row number) and stores his name and corresponding FIRST METRIC value, finds the player (B) who has the lowest/minimum value of the FIRST METRIC (if there is more than one with that value, pick the first one - lowest row number) and stores his name and corresponding FIRST METRIC value, computes FIRST METRIC average for all players, finds SECOND METRIC value for both players found above, computes SECOND METRIC average for all players,
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). The function prototype should be:bool is_match(const char *s, const char *p) Some examples:is_match("aa","a") → falseis_match("aa","aa") → trueis_match("aaa","aa") → falseis_match("aa", "a*") → trueis_match("aa", ".*") → trueis_match("ab", ".*") → trueis_match("aab", "c*a*b") → true""" def is_match(str_a, str_b): """Finds if `str_a` matches `str_b` Keyword arguments: str_a -- string str_b -- string """ len_a, len_b = len(str_a) + 1, len(str_b) + 1 matches = [[False] * len_b for _ in range(len_a)] # Match empty string with empty pattern matches[0][0] = True # Match empty string with .* for i, element in enumerate(str_b[1:], 2): matches[0][i] = matches[0][i - 2] and element == '*' for i, char_a in enumerate(str_a, 1):…

Write programs with these input and output Given positive integers m and n, find the number of ontofunctions from a set with m elements to a set with n elements.
(Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.
For the definition of x ∈ EXPR , na(x) denotes the number of a’s in the string, and we will use nop(x) to stand for the number of operators in x (the number of occurrences of + or ∗). Show that for every x ∈ EXPR, na(x)= 1 + nop(x).
Write a regular expression for the set of strings over the alphabet {a, b} that have at least one a andat least one b. For example, aaaba and bbaba are strings in the set, but aaaa and bbb are not.
Briefly explain why getline() is preferably used to capture string values, instead of the usual cin. Show an example of the getline() function and the example of input it would accept, that such input as cin would not accept.
a) Explain in your own words why the stringSort function will return a string with the characters of s sorted in ascending order, for any string s.
Write up what the properties of sets, lists, vectors and strings are and whether they are mutable or immutable. Then consider the class of problems that they are best for and use some code to illustrate your points. E.g., if you have a function that solves a problem using lists, then you can say why you can/can’t use vectors for it or sets etc?
