Frequencies by Hashing — an interactive walkthrough Java · DSA · Hashing Counting frequencies by hashing — and where the array should live A working int[] hash-array solution, traced against three inputs, plus the actual reason people move big arrays outside main() . Play with the bucket hasher below before you read a line of code. 🪣 The bucket hasher Type an array — watch it drop into indexed buckets, live. Array (space separated) Queries (space separated) Hash it Every value becomes an index. hash[value]++ drops a ball in that bucket — no comparisons, no searching, just direct addressing. That's the whole trick. 01 The working solution This is a correct, minimal frequency counter. It sizes hash to n + 1 , which works cleanly as long as every value fits within that range.
