There are n lines of strange number strings, where line 1 is 0, then line n is obtained by replacing character 0 with 01 and character 1 with 10 in line n-1. For example, the first row is 0, the second row is 01, the third row is 0110... Given the number of lines n and the number k, ask to output the kth number of the strange number string of the nth line. enter: The first input number n represents the number of rows, and the second number k is the required number. output: The kth digit of the strange digit string on the nth line. 1

For Loop Code in Java (more details in the pic below)
Write a program that will ask how many number of integers to input (n) and it will read in integer's nth times. Then the program will display the all positive integers and all negative integers and its sum, separately. Refer sample run below. Sample Run: Enter number of integers to be entered: 4 Enter integer 1:2 Enter integer 2: -1 Enter integer 3: -6 Enter integer 4: 13 The following positive integer/s: 2, 13 The sum of the positive integers: 15 The following negative integer/s: -1, -6 The sum of the negative integers: -7
Write a program that reads from the user a character ('s' or 'a'). If the character is 's', the program reads 4 numbers from keyboard and then finds their sum. If the character is 'a the program reads 4 numbers from keyboard and then finds their average. Ötherwise, it prints "Wrong character Sample Run: Sample Runl: Enter a character (s or a) : s Input 4 numbers: 10.5 12 31 44 The sum of these 4 numbers is: 97.5 Sample Run2: Enter a character (s or a): a Input 4 numbers: 10 12 31 44 The average of these 4 numbers is: 24.375 Sample Run3: Enter a character (s or a): d Wrong character
Given a positive integer 'n', find and return the minimum number of steps that 'n' has to take to get reduced to 1. You can perform any one of the following 3 steps:1.) Subtract 1 from it. (n = n - 1) ,2.) If its divisible by 2, divide by 2.( if n % 2 == 0, then n = n / 2 ) ,3.) If its divisible by 3, divide by 3. (if n % 3 == 0, then n = n / 3 ). Write brute-force recursive solution for this.Input format :The first and the only line of input contains an integer value, 'n'.Output format :Print the minimum number of steps.Constraints :1 <= n <= 200 Time Limit: 1 secSample Input 1 :4Sample Output 1 :2 Explanation of Sample Output 1 :For n = 4Step 1 : n = 4 / 2 = 2Step 2 : n = 2 / 2 = 1 Sample Input 2 :7Sample Output 2 :3Explanation of Sample Output 2 :For n = 7Step 1 : n = 7 - 1 = 6Step 2 : n = 6 / 3 = 2 Step 3 : n = 2 / 2 = 1 SolutionDp///.
You will be reading in a series of names from the keyboard. Count how many matching pairs there are – a matching pair is when two consecutive names are equal regardless of their case - and print the pairs. Input stops when the word ‘end’ is entered (also ignoring case). For example, Jack Jose jose Faith Robert Cynthia cynthia Cynthia Pierre ENd would print: Jose jose Cynthia cynthia cynthia Cynthia There were 3 matching pairs.

in the United States, telephone numbers consist of a three digit area code followed by a seven digit local number. Suppose neither the first digit of an area code nor the first digit of a local number can be a zero but that all other choices are acceptable. do not use commas when you write your number. For example enter 3356789 NOT 3,456,789
Use cin to read integer leftoverValue from input. Then, read the remaining integers from input until 99 is read. For each remaining integer read before 99, if the integer is positive, output the positive integer followed by a newline and subtract the positive integer from leftoverValue. Ex: If the input is: 57 -25 24 20 99 then the output is: 24 20 The total after subtracting all positive values is 13 Note: leftoverValue may go negative. 1 #include 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13} int inputData; int leftoverValue; *Your code goes here */ cout << "The total after subtracting all positive values is " << leftoverValue << endl; return 0;
Question 2: Write a program to read student ID and check whether it is odd/even number. Output a 4X4 badge if the student ID is even number and output a 3X3 badge if it is odd number. The badge is built up by the (height X width) of asterisks. (Use for-loop to draw the asterisks, do not hard-coded)
Python program: Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. (Hint: Use the % operator to extract digits, and use the // operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 // 10=93) Here is a sample run: Enter a number between 0 and 1000: 999 The sum of the digits is 27
In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
