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?

I am trying to convert a string in hexadecimal to an integer, or it's decimal value. For example A6 in hexadecimal is 166 in decimal. How do I do this without using modulus, division, and multiplication?
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).
What is the Huffman code for a string whose characters are all from a twocharacter alphabet? Give an example showing the maximum number of bits that couldbe used in a Huffman code for an N-character string whose characters are all from atwo-character alphabet.
Given a string S, determine whether it can be split into two non-empty palindrome strings. If yes, then output two palindrome strings A and B where the concatenation of A and B is S, i.e. S = A + B.If the answer is no, output NO c++ code stdio.h example : input : mnonm output: no, input : se output: s e

Given a string str, find the length of the longest substring without repeating characters. (a).For “ABDEFGABEF”, the longest substring are “BDEFGA” and “DEFGAB”, with length 6. (b).For “BBBB” the longest substring is “B”, with length 1.For “GEEKSFORGEEKS”, (c).there are two longest substrings shown in the below diagrams, with length 7 write code in python
Draw a DFA over the alphabet {a,b,c}that only accepts strings with no c's and an even number of a's, or an odd number of c's and an odd number of b's. For example, it should accept aa, aba, abbabaa, cbacabcb, cbcca, and abc but not aca, bacc, or aaa.
In C language, write a simple substitution code for an alphabetic string. That is, declare a permutation of the 26 alphabetic characters i.e. char perm[] = “qjczieaungsdfxmphybklortvw” Now, given a message string e.g. char msg[] = “secret message to encode”; Replace all occurrences of ‘a’ with ‘q’ (since perm[0]=’q’) Replace all occurrences of ‘b’ with ‘j’ (since perm[1]=’j’) Replace all occurrences of ‘z’ with ‘w’ (since perm[25]=’w’)So that, the message is modified to “bicyik fibbqai km ixcmzi” This programme should only convert lowercase letters. Any input character that is not a lowercase letter should be left unchanged.

Our usual number system is base 10, because it strings together the digits 0 – 9 to form any whole number (there is a 1’s place, a 10’s place, a 10-squared’s place, etc). Hexadecimal numbers are written in base 16. This means they string together the digits 0 – 9 and the letters A – F to form any whole number (there is a 1’s place, a 16’s place, a 16-squared’s place, etc). For example, BD3C8 and 305A2 are two different 5-digit hexadecimal numbers. How many 9-digit hexadecimal numbers are there that have exactly 4 zeroes. (Note: Hexadecimal numbers, like our normal base 10 numbers, cannot start with a 0)
