Welcome to Day 25 of the DSA Coding Challenge!
Today's Goals (Hash Tables):
- Hash Tables Data Structure Crash Course
Question 1: Two Sum - You are given an array of Integers and another integer targetValue. Write a function that will take these inputs and return the indices of the 2 integers in the array that add up targetValue.
Question 2: Isomorphic Strings - Given two strings s and t, determine if they are isomorphic. Two strings s and t are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character, but a character may map to itself. s and t consist of any valid ascii character.
All the best!
