Computing Algorithms

A computing algorithm is a set of instructions or a process for solving computational problems. In other words, it contains a set of rules that indicate the step-wise process to solve a problem. The algorithm takes a set of inputs, executes the instructions given to it, and produces the desired output.

Consider the relation R3 on P({0, 1, 2, 3}) such that (A, B) E R3 if and
only if the sum of elements in A is equal to the sum of elements in B and if A and B
are nonempty then the largest element in A equals the largest element in B. (That is,
R3 = Rị n R2 from question 1.)
Select all that are true:
O a) R3 is reflexive
O b) R3 is symmetric
c) R3 is transitive
d) R3 is an equivalence relation

A company has a large number of documents that need to be sorted into one of three categories: Research & Development, Finance or Marketing. They have been able to identify a number of phrases which are commonly used in these documents and may help disambiguate them but there are a large number (thousands) of these phrases and each one only appears in a small number of documents. Thankfully someone has labeled a few hundred documents for you but you need to design an algorithm to automatically label the rest.

Python code not working, please check my code. Here is the question it is based off: Building and using DNA Motifs Background Sequence motifs are short, recurring (meaning conserved) patterns in DNA that are presumed to have a biological function. Often they indicate sequence-specific binding sites for proteins and other important markers. However, sometimes they are not exactly conserved, meaning some mutations can happen in a motif in a particular organism. Mutations can be DNA substitutions/deletions/insertions. Therefore, sequences are usually aligned and a consensus pattern of a motif is calculated over all examples from organisms. The following are examples of a transcription factor binding (TFB) site for the lexA repressor in_ E.
