Hashing
Pairs that sum to k
AskAI
Given an array of integers and a value k, print all pairs that sum to k.
Two-Sum Hashing
AskAI
The Two-Sum Hashing problem is to find two numbers in an array that add up to a given target number. This can be solved using a hash table, which stores the array elements and their corresponding indices. To find two numbers that add up to the target, we can iterate through the array, and check if the complement (target - array[i]) exists in the hash table. If it does, then we have found our two numbers.
Longest Common Prefix
AskAI
The longest common prefix problem is to find the shortest string that is a prefix of all the strings in a given array.
Sum of the Two Largest Values in a List
AskAI
This problem asks you to return the sum of the two largest values in a given list of positive integers. For example, given the input [1, 2, 3, 4, 5], the correct output would be 9 (since 3 + 6 = 9).
Two numbers that add up to the target sum
AskAI
Given a list of integers and a target sum, return the two numbers from the list that add up to the target sum.
Find the two numbers with the largest sum in an array of integers.
AskAI
Given an array of integers, this algorithm finds the two numbers that have the largest sum and returns that sum. For example, in the input array [1, 2, 3, 4, 5], the algorithm would return 9 (as the two largest numbers are 4 and 5, whose sum is 9).
Two numbers that add up to a given target number
AskAI
Given an array of integers and a target number, this problem asks to find the two numbers in the array that add up to the target. For example, given an array of [2, 7, 11, 15] and a target of 9, the solution would be [2, 7].
