在codewars上練習到的題目
get Highest and Lowest number from string of space separated numbers
本來想說用 Arrays.stream.mapToInt 再找出最大和最小二個int
後來解完發現有神人用 collectors 一行就完成了
記錄一下
IntSummaryStatistics summary = Arrays.stream(numbers.split(" "))
.collect(Collectors.summarizingInt(n -> Integer.parseInt(n)));
return String.format("%d %d", summary.getMax(), summary.getMin());
determine strings that include numbers and spaces differ from Highest and Lowest numbers inside strings that includes spaces
