We could use two hash sets, one for each array, then do intersection on both sets; Slight modification: use the second set to hold all intersection elements rather than all distinct elements in the second array; Solution 2. We can sort one of the two arrays, then use binary search to find intersection elements; Solution 3. We can sort both arrays, then use two pointers to iterate through both of the sorted arrays. // TOOLS THAT I USE: ○ Memory Foam Set Keyboard Wrist Rest Pad - https://amzn.to/3cOGOAj ○ Electric Height Adjustable Standing Desk - https://amzn.to/2S9YexJ ○ Apple Magic Keyboard (Wireless, Rechargable) - https://amzn.to/36gy5FJ ○ Apple Magic Trackpad 2 (Wireless, Rechargable) - https://amzn.to/36ltimu ○ Apple MacBook Pro - https://amzn.to/30iSvKE ○ All-In One Printer - https://amzn.to/34etmSi ○ Apple AirPods Pro - https://amzn.to/2GpVYQf ○ My new favorite Apple Watch - https://amzn.to/2EIIUFd // MY FAVORITE BOOKS: ○ Introduction to Algorithms - https://amzn.to/36hxHXD ○ Designing Data-Intensive Applications - https://amzn.to/2S7snOg ○ Head First Java - https://amzn.to/2ScLDKa ○ Design Patterns - https://amzn.to/2SaGeU2 Follow me on Github for complete LeetCode solutions: https://github.com/fishercoder1534/Leetcode Support me on Patreon: https://www.patreon.com/fishercoder My ENTIRE Programming Equipment and Computer Science Bookshelf: https://www.amazon.com/shop/fishercoder And make sure you subscribe to my channel!
