Your solution is having O(n^2) complexity due to two nested for loops which are not efficient to solve this problem you can optimize it further. simpleArraySum has the following parameter (s): ar: an array of integers Here are two numbers i.e. Initialize s to 0. Otherwise, print the person's name and phone number. 1 <= n <= 100000 1 <= Query <= 100000 Output Format. Yesterday, puppy Tuzik learned a magically efficient method to find the sum of the integers from 1 to N. He denotes it as sum (N). Initialize a number s which represents sum of all the number in the array. Now, iterate over the range [1, K] using a variable i and perform the following steps: Iterate over the range [1, N], using a variable j, and update the value of dp [j] as dp [j]+ dp [j - i], if j i. 1007 1229 Add to List Share. For example, one might opt for case-insensitive search, or to display only the fragment matching the specified search pattern, or to display only the line number of an input file where the specified string or . by executing `no more` than the limited number of swaps. Examples : Input : arr = {1, 5, 6}, N = 7 Output : 6 Explanation:- The different ways are: 1+1+1+1+1+1+1 1+1+5 1+5+1 5+1+1 1+6 6+1 Input : arr = {12, 3, 1, 9}, N = 14 Output : 150 Solution. Generic methods are a very efficient way to handle multiple datatypes using a single method. In this post we will be solving the HackerRank Largest Permutation problem using the Java programming language, the VSCode IDE and a Windows computer. We need an optimized approach. Some ideas that can improve the complexity: I am seeing that you are trying to equate num to i + (i+1) + . The idea is to use recursion to solve this problem.
