I am considering the matric number as 2210039 Now x = 221 and y - 039 we change 0 in y as 2 so, x =…

2. Let x be the first three digits of your matric number, AND y be the last three digits of your matric number. If the first digit of y is 0, replace it with 2. Example: If you matric number is 2013034, Thus, x = 201 and y 234 a. Write the values of x and y based on your matric number. b. If a = x (mod 7) and b = (-1) • y (mod 7), find the integer(s) c with 10 < c < 20 such that c = a + b² (mod 7) c. Show all the steps to calculate LCM (x, y) using prime factorization.

One variation on the game of nim is described in Luger. The game begins with a single pile of stones. The move by a player consists of dividing a pile into two piles that contain an unequal number of stones. For example, if one pile contains six stones, it could be subdivided into piles of five and one, or four and two, but not three and three. The first player who cannot make a move loses the game. (5.1) Draw the complete game tree for this version of Nim if the start state consists of six stones. (5.2) Perform a minimax evaluation for this game. Let 1 denote a win and 0 a loss.
Please Answer in C++ only A Rajesh teaches a cooking class. The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Input 1 1 hasan jaddouh Output hasan

Please answer in c++ only In Chefland there is a competition with N participants (numbered 1 to N). There are N-IN-1 rounds in the competition; in each round two arbitrarily selected contestants will compete, one of them will lose and be eliminated from the competition. There are 10 weapon types (numbered 1 to 10). You are given the N strings s1,s2,s3.....sn. for each valid i and j, the jth character of Si is '1' if it has ii. contestant originally weapon of type jj or '0' otherwise. During each battle, for each type of j such that both contestants in that battle currently have type j weapons, those weapons of both contestants are destroyed; after the battle, the winner collects all remaining (undestroyed) weapons of the loser. Remember that each competitor can win or lose regardless of the weapons they have. The chef is bored watching the competition, so he wants to find the maximum possible number of weapons that the winner of the tournament could have after the last battle,…
