Accessing characters in string:

• In Python, there are two techniques for accessing characters present in string.

○ Using “for” loop.

■ Each time the loop operates, variable will refer a copy of character in the string that begins with the first character.

○ Using indexing.

■ The characters can be accessed using index.

■ Each character of a string has an index that specifies the string’s position.

■ Indexing starts at 0 and ends with a count of one less than the total number of characters in a string.

Objective you will: 1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five) 2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector. 3. Compare the performance of TreeSort with C++'s std::sort on large datasets. Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST): 1. Insert all elements into a BST (logically sorting them). 2. Traverse the BST in-order to extract elements in sorted order. 3. Store the sorted elements in a vector. Time Complexity Operation Average Case Worst Case (Unbalanced Tree)Insertion 0(1log n) 0 (n)Traversal (Pre-order) 0(n) 0 (n)Overall Complexity 0(n log n) 0(n^2) (degenerated tree) Note: To improve performance, you could use a…

I need help fixing the minor issue where the text isn't in the proper place, and to ensure that the frequency cutoff is at the right place. My code: % Define frequency range for the plot f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz w = 2 * pi * f; % Angular frequency % Parameters for the filters - let's adjust these to get more reasonable cutoffs R = 1e3; % Resistance in ohms (1 kΩ) C = 1e-6; % Capacitance in farads (1 μF) % For bandpass, we need appropriate L value for desired cutoffs L = 0.1; % Inductance in henries - adjusted for better bandpass response % Calculate cutoff frequencies first to verify they're in desired range f_cutoff_RC = 1 / (2 * pi * R * C); f_resonance = 1 / (2 * pi * sqrt(L * C)); Q_factor = (1/R) * sqrt(L/C); f_lower_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) + 1/(2*Q_factor)); f_upper_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) - 1/(2*Q_factor)); % Transfer functions % Low-pass filter (RC) H_low = 1 ./ (1 + 1i * w *…
