第二题 public static void main(String[] args) { int []a = {5,4,3,3,2,4}; int len = 1; int max = 0; boolean flag = true; for (int i = 1; i < a.length; i++) { if (a[i] < a[i - 1] &;&; flag) { len++; continue; } else if (a[i] > a[i - 1] &;&; len > 1) { flag = false; len++; max = Math.max(max, len); } else { len = 1; flag = true; } } System.out.println(max); }
