Ask HN: Recommended course/website/book to learn data structure and algorithms

3 points by strikeX 9y ago

I am a full-time Android developer who does most of his programming work in Java. I am a non CS graduate so didn't study Data structure and algorithms course in university so I am not familiar with this subject which is hindering my prospect of getting better programming jobs. There are so many resources out there on this subject that I am unable to decide which one is the best for my case. Could someone please point me out in the right direction. Thanks.

Steven Skiena is quite good. Practical and not too much into the Math. CLRS is good for reference.

While perusing awesome-awesomeness [1], I found awesome-algorithms [2] , algovis [3], and awesome-big-o [4].
