- Write the following function to check whether a string is a palindrome assuming letters are case-insensitive: bool isPalindrome(const string& s) Write a test program that reads a string and displays whether it is a palindrome.a) Design a regular expression that accepts the language of all binary strings which their length is odd with no occurrences of 11. b) Design a regular expression that accepts the language of all binary strings with no occurrences of 001.Python Language Useful websites: : http://en.wikipedia.org/wiki/Radix http://www.purplemath.com/modules/numbbase.htm Special Rules: Use only Boolean/math expressions and conditional statements (if-statements). Do not use built-in functions for converting integers into a string representation. Here to start with: kthDigit(x: int, b: int, k: int) -> int .........
- 1.a. Write a Regular Expression Language over ∑ = {a,b,c} a set of strings terminated by a or b. .b. Write a regular expression for the set of binary strings where each string has at least one pair of consecutive zeros. c. write the regular expression for the following, where sigma = (a,b): i. string of length at least 2 ii. string of length at most 2 iii. all string starting with a and ending with b iv. Even length StringsConsider the two regular expressions, L1 = a* + b* and L2 = ab* + ba* + b*a + (a*b)* a) Find a string corresponding to L, but not L2. b) Find a string corresponding to L2 but not L1 c) Find a string in {a,b}* corresponding to neither L1 nor L2.Question 3 Regular expression for all strings starts with ab and ends with bba is. a) aba*b*bba b) ab(ab)*bba c) ab(a+b)*bba d) (ab)*bba
- python: a function that counts the number of occurrences of given character in a given string. For example, calling the function with Count(‘j’, ‘just joshin’) returns 2. Note the function counts the character regardless of case.CODE USING C++ Can you identify if Cody's name is spelled right? If so, then make a program that accepts four one-letter strings separated by space and print "Correct" if the inputted strings, combined in order, spell the name Cody correctly. If not, print "Wrong". It doesn't matter if it's in uppercase or lowercase, as long as it's spelled correctly, it's considered correct. Now, will you take on this task? Input A line containing four one-letter strings separated by a space. c·O·D·y Output A line containing a string. CorrectEnter two strings and check whether one string is the reverse of other or not. For example, consider the strings “vikas” and “sakiv”, you can notice that one string is the reverse of other(IN C LANGUAGE)
- Convert int to string without the itoa function. This is C programming.String to integer ATOI (requires use of INT_MAX and INT_MIN): Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) is '-' or '+'. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored. Convert these digits into an integer (i.e. "123" -> 123, "0032" -> 32). If no digits were read, then the integer is 0. Change the sign as necessary (from step 2). If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then clamp the integer so that it remains in the range. Specifically, integers less…Q2/ (a) A student is given 3 tests, each marked out of 100. The student passes if his average mark is greater than or equal to 50 and fails if his average mark is less than 50. Prompt for the 3 marks and print pass if the student passes and fail otherwise. Write a program in C language to solve this.
