Find a system of recurrence relations for the number of n-digit quaternary sequences that contain an even number of 2’s and an odd number of 3’s.

Find a system of recurrence relations for the number of n-digit quaternary sequences that contain an even number of 2’s and an odd number of 3’s. Define the initial conditions for the system. (A quaternary digit is either a 0, 1, 2 or 3)

Suppose the alphabet is S = {A B C D} and the known probability distribution is PA = 0.3, PB = 0.1, PC = 0.5, and PD = 0.1. Decode the Huffman coding result {11000010101110100} to the original string based on the probability distribution mentioned above. The codeword for symbol “D” is {111}. Please writing down all the details of calculation.

For simplicity, you can consider DNA sequences as strings in the alphabet of {A, C, G, T}. Implement a special hash table to store all short DNA segments of certain length (e.g., 20) found in a long DNA sequence. Every DNA segment is stored as a (key, value) pair, where the key is the sequence of the segment, and the value is the position of the segment in the DNA. For example given a DNA sequence of ACGTACGTTT, there are...

Let the natural number n have the decimal numeral 123,461,46d, where d is the units digit. Use divisibility tests to give all of the choices of d by which n is divisible. Complete parts (a) through (h) below. (a) For what value(s) of d is n divisible by 2? (Use a comma to separate answers as needed.) (b) For what value(s) of d is n divisible by 3? (Use a comma to separate answers as needed.) (c) For what value(s)...
