Interview Challenges in Decoding Arrays
In the realm of coding challenges, array manipulation issues have proven to be a popular and intriguing category. This list, ranging from simple to difficult, presents a variety of problems that will test your coding skills.
Easy problems include finding the second largest and third largest elements, reversing an array, and moving all zeroes to the end of an array. Other easy tasks involve creating a wave array, increasing the value of an array by 1 (Plus One), and finding the maximum consecutive ones.
Medium difficulty problems delve into more complex tasks such as finding the next permutation, the majority element, the majority element II, minimizing heights, and maximizing and multiplying subarrays. The Jump Game, which involves deciding whether you can jump from the start to the end of an array with a given step limit, also falls into this category.
As we progress to the hard problems, we encounter the Smallest Non-Representable Sum in Array, Closest Subsequence Sum, and Trapping Rain Water. These problems require a deeper understanding of array manipulation and algorithmic thinking to solve.
Maximum Sum Among All Rotations, Maximum Circular Subarray Sum, and Count Subarrays with K Distinct Elements are other challenging problems on the list. The Smallest Range Having Elements From K Lists and Smallest Missing Positive Number are also included, requiring a more sophisticated approach to solve.
The list also includes problems related to stock trading, such as buying and selling stocks with one or multiple transactions. Problems like finding the longest mountain subarray, rearranging array elements by sign, and the Next Smallest Palindrome round off the list of hard problems.
This comprehensive list offers a great opportunity for coders to hone their skills and tackle a variety of interesting and challenging problems in the field of array manipulation.
