In MATLAB, primes(N) provides all the prime numbers less than or equal to N. E.g. primes(15) = [2 3 5 7 11 13]. The sum of the first digit of each prime is 19 (i.e. 2+3+5+7+1+1 = 19).
What is the sum of the first digit of all primes less than or equal to 55555? You may want to use the num2str() function.
Please use matlab

Specifically for the purpose of this question, 0 and 1 are notconsidered composite numbers.Your machine can be non-deterministic, and it can use multiple tapes (as many as you need). I suggestbreaking up the construction into smaller sub-tasks. In particular, the machine you built in Question 3might be useful.For this question, it is enough to give a detailed description of the algorithm of your machine. You donot need to draw a full transition diagram. Although you can draw diagrams for smaller parts if it helpsyou illustrate your construction.arrow_forwardGive a recursive definition for the set of all strings of a’s and b’s that begins with an a and ends in a b. Say, S = { ab, aab, abb, aaab, aabb, abbb, abab..} Let S be the set of all strings of a’s and b’s that begins with a and ends in a b. The recursive definition is as follows – Base:... Recursion: If u ∈ S, then... Restriction: There are no elements of S other than those obtained from the base and recursion of S.arrow_forward
- Solved in pythonarrow_forwardImagine you have 331 sheep, and you are going to use primitive counting to write a tally stick for the King. Suppose you carry out the procedure as usual, filling the pens with sheep, and liberating the sheep from pen 2 (and any extra sheep); then doing it again, doing it again, etc., until you get down to one sheep.How many sheep will you have in the first pen After one round? After two rounds? After three rounds?arrow_forwardIn MIPS assembly, implement integer division using rounding (rather than truncation). This is accomplished by taking the remainder of the division and dividing it by the original divisor. If the new quotient is higher than or equal to one, multiply it by one.Otherwise, leave the original quotient alone.In MIPS assembly, implement integer division using rounding (rather than truncation).

The letters A and T are complements, and the letters Cand G are complements. To find the complement of a DNA strand you must replace eachcharacter with its complement. For example, ATCGG is the complement of TAGCC andCCC is the complement of GGG. Your program must show a DNA of a predefined lengthto the player and ask for its complement.2. Find the reversed DNA strand: the order of the characters in a DNA strand should bereversed. Examples: GCTAA is the reverse of AATCG and AA is the reverse of AA. Yourprogram must show a DNA of a predefined length to the player and ask for the reversedstrand.3. Find the compressed DNA strand: all repeated characters in a DNA strand should bereplaced by the number of repeats followed by that character once. For example, 2C3ATis the compressed…arrow_forward
