Consider the hex strings A=0xee89e74b88a069db and B=0x2f b6965993e7af84. a) What is A O B in hexadecimal? Please give your answer a leading 0x and use lowercase letters only. Make sure you use exactly 16 hex digits (which may involve typing in leading zeros). hexadecimal: b) Suppose that A was generated uniformly at random from all 8 byte strings. What is the probability that the second binary digit of A is 1? c) Suppose that A was generated uniformly at random from all 8 byte strings. What is the probability that the second binary digit of A O B is 1?

Given two strings, s1 and s2, select only the characters in each string where the character in the same position in the other string is in uppercase. Return these as a single string. To illustrate, given the strings s1 = "heLLo" and s2 = "GUlp", we select the letters "he" from s1, because "G" and "U" are uppercase. We then select "Ip" from s2, because "LL" is in uppercase. Finally, we join these together and return "help". Examples selectLetters("heLLO", "GUlp") "GUlp") → "help" selectLetters("1234567", "XxXxX") → "135" wwwwwwwwwww. selectLetters("EVERYTHING", "SomeThings")→ "EYSomeThings"

This question is revolved around the testing of a well-known chef Gordan Ramsay analytical skill the chef prefers the strings but prefers palindromic strings. Today he found an old rope in his garage. The string is so old that some of its characters have run out and are now unknown. The characters that end in the string are represented by '' and some letters are lower Latin alphabets i.e. ['a' - 'z']. A palindrome-loving chef has decided to create the smallest named palindrome by filling in each finished letter (".") In a small Latin alphabet. Can you help her finish the job by providing the C++ program for that? Example Input: 3 a.ba cb.bc Output: a.babba cbabc -1

Problem: Write a C++ program that would implement the function called roman Tolnt which returns the integer equivalent of a given string s in Roman numeral. Roman numerals are represented by seven different symbols each with corresponding values: I 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000. - Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five, we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. . X can be placed before L (50) and C (100) to make 40 and 90. . C can be placed before D (500) and M (1000) to make 400 and 900.
Write a program that uses two nested for loops and the modulus operator (%) to detect and print all prime numbers from 1 to 10,000. Prime numbers are integral numbers that are only evenly divisible by themselves and one (1). Display all the prime numbers found.
