Programs

The programs are listed in no specific order.

  1. is prime number: A program that takes in a number and outputs whether its a prime number or not.
  2. factors: Take in a number from user. Output all of its factors.
  3. n-th factorial: A program that takes in a number and outputs n-th factorial.
  4. is perfect number: A program that takes in a number and outputs whether its a perfect number.
  5. fibonacci numbers: A program that takes in a number and prints all fibonacci numbers less than or equal to .
  6. determinant of matrix: Take in a matrix from user. Output the determinant of the matrix. First try for . Then go higher-ordered matrices.
  7. pascal’s triangle: Take from user input. Print pascal’s triangle to rows.
  8. is valid palindrome: Take a string input from user. Output if the input is palindrome or not. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Try not to use [::-1].
  9. armstrong numbers: Take from user input. Print all armstrong numbers (in base 10, of course) between 0 and (inclusive).
  10. letter analysis: Take a text input from user. Find how many times each letter is being used in that string. Use a dictionary to store the data. Output the final results. Try to read the text from a .txt file as well.
  11. word length analysis: Take a string input from user. Print length of each word separated by a space. Try to include the summary using a dictionary.
  12. letter expanding: A program that converts b3j8k2 to bbbjjjjjjjjkk. The number can be 1 to 99.
  13. binary addition: Take in 2 numbers in binary (as strings) and output the sum of both numbers. Try not to use bin function.
  14. big integer addition: Given a very large integer represented as a list, where each digits[i] is the digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. Increment the large integer by one and return the resulting array of digits. Don’t construct a int object.
