The problem asks for a sum of integers that are hashed to odd values. An example input is given, and the expected output is 9.
Given a list of integers and a target sum, this problem determines whether any two integers in the list sum to the target sum. For example, given the input [1, 2, 3 , 4, 5] and target sum = 9, the output would be true because 4 + 5 = 9.
This problem asks us to write a function that takes in a string and returns True if the string has all unique characters, and False if it does not.
This problem asks for the implementation of a hash table in Java. The input is a set of keys to be stored in the hash table, and the output is the hash table containing the keys .
Given a string, this function returns the first non-repeating character in the string. For example, given the input string "abcab", the function would return "c".
This problem asks whether a given list of integers contains a pair of numbers whose sum equals a given target value. For example, if the list is [1, 2, 3, 4, 5] and the target value is 6, the answer would be True (1 + 5 = 6).
This problem can be solved using a hashing approach. We can iterate through the array, adding each element to a hash table. Then, for each element, we can check if there is another element in the array that adds up to the target number. If so, we return the indices of the two numbers.
