The list can be accessed at this link. Initially, I solved each problem using a brute-force approach, which often resulted in a Time Limit Exceeded (TLE) error. Then, I solved each problem with an optimized method that was accepted on LeetCode. For every problem on the list, I have provided both the naive brute force solution and an optimized solution. https://blog.sksoumik.com/software-engineering/all-leetcode-two-sum-problem-variations-with-python-solutions/ Fri, 21 Oct 2022 00:00:00 +0000 https://blog.sksoumik.com/software-engineering/all-leetcode-two-sum-problem-variations-with-python-solutions/ Author: Sadman Kabir Soumik Original Two Sum Problem Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. 1Example 1: 2Input: nums = [2,7,11,15], target = 9 3Output: [0,1] 4Explanation: Because nums[0] + nums[1] == 9, we return [0, 1]. https://blog.sksoumik.com/software-engineering/basic_coding_problems_that_you_must_know_as_a_cse_graduate/ Fri, 22 Feb 2019 00:00:00 +0000 https://blog.sksoumik.com/software-engineering/basic_coding_problems_that_you_must_know_as_a_cse_graduate/ Check Prime Number A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. For example, the first six prime numbers are 2, 3, 5, 7, 11, and 13. The number 6 is not a prime number because it has more than two positive integer divisors. In fact, the divisors of 6 are 1, 2, 3, and 6. To determine if a number is prime, you can check if it has any positive integer divisors other than 1 and itself.
