- Given string inputString on one line and integers idx1 and idx2 on a second line, output "Match found" if the character at index idx1 of inputString is equal to the character at index idx2. Otherwise, output "Match not found". End with a newline. Ex: If the input is: banana 1 3 then the output is: Match found Note: Assume the length of string inputString is greater than or equal to both idx1 and idx2. import java.util.Scanner; public class CharMatch { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String inputString; int idx1; int idx2; inputString = scnr.nextLine(); idx1 = scnr.nextInt(); idx2 = scnr.nextInt(); /* Your code goes here */ }}arrow_forwardThe following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna): for c in dna: if c in 'acgtACGT': return True else: return False B) def valid_dna3(dna): for c in dna: flag = c in 'acgtACGT' return flag C) def valid_dna4(dna): for c in dna: if not c in 'acgtACGT': return False return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 onlyarrow_forwardString: abcdefghijklmnopqrstuvwxyzyxwvutsr qponmlkjihgfedcba Make a program that: reads a letter from standard input print the above string up to this letter For example, if the letter was c, the output would be: abcba Must use a function and Pythonarrow_forward
- Code should be in Python. Prompt the user to enter a string of their choosing. Output the string.Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Complete the get_num_of_characters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. Extend the program by calling the get_num_of_characters() function and then output the returned result. Extend the program further by implementing the output_without_whitespace() function. output_without_whitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the output_without_whitespace() function in main().Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: Theonlythingwehavetofearisfearitself.arrow_forward[CelsiusTemperature Table] The formula for converting a temperature from Fahrenheit to Celsius is C = 5/9 * (F - 32) where F is the Fahrenheit temperature and C is the Celsius temperature.Write a function named celsius that accepts two Fahrenheit temperatures (low and high) as arguments. The function will print a table list the Fahrenheit temperatures from low to high and the corresponding Celsuis temperatures. What is the function prototype? (assume only integers used for the temperate) void celsius (int, int); How to implement this function? The function will use a loop to convert the Fahrenheit temperatures to Celsius temperatures and display the values in the console. In the driver program, prompt for the user input for the low and high Fahrenheit temperatures. Call the the function to display the result in the console. Requirements: Use only for-loop for this exercise; Print the output in a table format Include the function prototypes before the main() All functions…arrow_forwardJAVAarrow_forward
