Time complexity of this solution is O(limit 3) where ‘limit’ is given limit.Īn Efficient Solution can print all triplets in O(k) time where k is number of triplets printed. For every triplet, check if Pythagorean condition is true, if true, then print the triplet. Input : limit = 20Ī Simple Solution is to generate these triplets smaller than given limit using three nested loop. Given a limit, generate all Pythagorean Triples with values smaller than given limit. Ques: A Pythagorean triplet is a set of three integers a, b and c such that a 2 + b 2 = c 2. Given an array of integers representing the color of each sock, determine how many pairs of socks with matching colors there are.įor example, there are n=7 socks with colors ar = There is a large pile of socks that must be paired by color for sale.

LinkedHashMap maintains the order of insertion.

But, we can sort the entries based on value and store into LinkedHashMap. So, sorting its entries doesn’t make any sense. public class StringPrograms įor (int i = 0 i list1 = new ArrayList() We can append the characters to a string builder and finally return the reversed string. We can create a character array from the string and then iterate it from the end to start. It might be surprising, but there is no reverse() utility method in the String class. If you can write Java programs using the latest features, it means you keep yourself up to date, which will work in your favor. Write an efficient method that takes stockPrices and returns the best profit I could have made from one purchase and one sale of one share of Apple stock yesterday.
