WebA (bounded) queue can be easily implemented using an array using a five elements structure: structure stack: item : array. maxsize : integer. front : integer. rear : integer. size : integer. Since fixed-length arrays have limited capacity, we need to convert the array into a closed circle. If n is the array’s size, then computing indices ... http://geekdaxue.co/read/tendermint-docs-zh/spec-reactors-consensus-proposer-selection.md
