Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers.

  • The problem is to find the next higher number of the given input number using the same digits.
  • The problem can be solved using a brute force approach, direct solution, or by using an inbuilt function.
  • The direct solution involves finding two pointers, swapping the numbers, and sorting the array.
  • It is also possible to solve the problem using the 'next_permutation()' function in the C++ STL.

Letter Combinations of a Phone Number

  • Given a string containing digits from 2-9 inclusive, return all possible letter combinations that the number could represent.
  • Solution 1: Iterative method: In this method, we shall be taking 3 for loops.
  • Pass 1 of digits_loop : chars = digit_letter_mapping[digits[i] - '0']; chars ="abc" characters_loop run for 3 times pass 1 of characters_loop combination_loop run for 1 time temp = a pass 2 of characters_loop combination_loop run for 1 time temp = b pass 3 of characters_loop combination_loop run for 1 time temp = b
  • Pass 2 of digits_loop : chars = digit_letter_mapping[digits[i] - '0']; chars ="abc" characters_loop run for 3 times pass 1 of characters_loop combination_loop run for 3 time pass 1 of characters_loop temp = ad pass 2 of characters_loop temp = bd pass 3 of characters_loop temp = cd pass 2 of characters_loop combination_loop run for 3 time pass 1 of characters_loop temp = ae pass 2 of characters_loop temp = be pass 3 of characters_loop temp = ce pass 3 of characters_loop combination_loop run for 3 time pass 1 of characters_loop temp = af pass 2 of characters_loop temp = bf pass 3 of characters_loop temp = cf
  • Solution for iterative method in C++
  • Backtracking method: Using backtracking method, the solution is very simple.
  • The solution is based on the fact that; if length of the letter combination is equal to the length of the digits, we shall write it in our final result set.
  • Out backtrack function “get_combination_backtrack” takes 5 parameters: Mapping of letters and digits, Final result set, Local variable for storing intermediate result, Start index and Digits from input.
  • Example: Input: “23” Output: [“ad”, “ae”, “af”, “bd”, “be”, “bf”, “cd”, “ce”, “cf”].

Fortinet warns of malicious Python packages targeting credentials and user data

  • Fortinet Inc.'s FortiGuard Labs has discovered two malicious Python packages that pose a high risk of credential theft, data exfiltration, and unauthorized system access.
  • The first vulnerability, Zebo-0.1.0, exhibits sophisticated malware behavior, including keylogging, screen capturing, and data exfiltration to remote servers.
  • The second vulnerability, Cometlogger-0.1, targets system credentials and user data, evades detection, and can steal a wide array of user data.
  • To prevent infection, it is recommended to verify third-party scripts, implement firewalls and intrusion detection systems, and train employees to recognize phishing attempts.
