Data analysis and algorithms - sorting based answering of two questions (Q3 and Q4) -- 2

This is for a course on C++. There are two questions that need to be completed (namely Q3 and Q4). Answering of each question needs to be done with a word count of 400 words each. Appropriate diagrams need to be made in order to explain the answers. Each and every requirement of the question must be fulfilled in accordance with the instructions of the attached file. You must not be working on the same set of questions for anyone else and you cannot disclose the completed work to anyone else. Plagiarism is strictly forbidden. Your work will be checked through turnitin. Each question will require at least two references from articles published in journals in the last 5-10 years. Appropriate in-text referencing and referencing at the end must be carried out by following Harvard referencing style. Hence the total word count for answering the questions = 2 x 400 = 800 words (excluding references) The relevant Prac 5 code will be provided to you. However, the modified code that is required for Q3 and Q4 will need to be provided by you (some tips are already given in the questions themselves, for it)
