Operations of vector class

The vector class is available in Java and C++ programming languages. It is a class implementing a dynamic array. A dynamic array is an array whose size automatically increases when an element is added to it. The vector class stores elements in a contiguous memory block and assigns the memory to the elements whenever required during execution.

Problem DNA: Subsequence markingA common task in dealing with DNA sequences is searching for particular substrings within longer DNA sequences. Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…

create using c++ One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector . This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have the following A private member variable called dynamicArray that references a dynamic array of type string. A private member variable called size that holds the number of entries in the array. A default constructor that sets the dynamic array to NULL and sets size to 0. A function that returns size . A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray , copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the…
