In this blog post, we’ll explore the “Maximum Product Subarray” problem, where our task is to find the contiguous subarray within an array that yields the maximum product. We’ll discuss the problem statement in detail and explore two approaches: the brute force solution and an optimized solution using dynamic programming techniques.

Given an array of positive integers with some zeroes. You need to move all the zeroes to the end without changing the relative order of nonzero elements. A unique solution makes this problem really easy to understand.

Binary Search is a fabulous concept that can be used to narrow down the search range. One such problem on LeetCode explores this domain where you need to find the correct position to insert the element in a sorted array

Small problems like these often become a part of larger complex problems. You are given an array and for each integer you need to find out the number of smaller numbers than itself. One technique is to compare each element with every other element. Another efficient approach would be to use the counting sort approach.

Always make sure that we understand the problem statement first. There is an array of integers nums and we need to determine the number of good pairs. A pair (i , j ) is said to be good, if nums[i] == nums[j] and i < j. We need to determine how many pairs can we form that hold this condition. Let us look at some sample test cases: Input: nums = [ 1 , 2 , 3 , 1 , 1 , 3 ]Output: 4Explanation:There are 4 good pairs. (0…


A camel case is a special string representation in which the first word starts with a small letter, and all other words start with an upper case character. Given such a string, find the total number of words

Let us try to understand this problem statement first. We have some strings that needs to be super reduced in size. The string consists of english alphabets from a to z, and they can be duplicated at some places. If we see two adjacent characters that are same, they can be eliminated. Following this pattern we have to return a super compressed/reduced string. Let us look at some sample test cases: Input: aabcccddOutput: “bc”Explanation:aabcccdd > bcccdd > bcdd > bc(we eliminate two same adjacent characters at each step) Input: abbaOutput:…
