From JSON to Environment Variables: Introducing json-to-env-converter

json-to-env-converter is an npm package that converts JSON objects into environment variables.
It helps handle JSON-based configurations by converting them into environment variables and injecting them into process.env.
The package is useful for scenarios where configurations might be dynamic, nested, or sourced from APIs or external systems.
The tool allows for programmatically loading configurations at runtime without restarting the app.

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.
