Most Frequent Character Program plan: Include the required header files to the program. Declare function prototype which is used in the program. Define the “main()” function. Declare the required variables. Get the input C-string from the user and call the function “frequent_char” with the input C-string. Check the input has a frequent character. Print the result. Define the “frequent_char” function. Declare the required variable. Get the length of the string and set that length to array variable. Initially set all element of that array to 0. Calculate the frequencies of the character in that string. Finally return the result to the main function.

Question

I need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand. The problem is a 2×2 binary sudoku with two rules: • No column may contain the same value twice. • No row may contain the same value twice. Each square in the sudoku is assigned to a variable as follows: We want to design a quantum circuit that outputs a valid solution to this sudoku. While using Grover’s algorithm for this task is not necessarily practical, the goal is to demonstrate how classical decision problems can be converted into oracles for Grover’s algorithm. Turning the Problem into a Circuit To solve this, an oracle needs to be created that helps identify valid solutions. The first step is to construct a classical function within a quantum circuit that checks whether a given state satisfies the sudoku rules. Since we need to check both columns and rows, there are four conditions to verify: v0 ≠ v1 # Check top row v2 ≠ v3 # Check bottom row…
