Java实现的计算最大下标距离算法示例

public static int maxindexdistance(int A[]) {    boolean[] isDes = new boolean[A.length];    int min = A[0];    isDes[0] = true;    for (int i = 0; i < A.length; i++) {      if (A[i] < min) {        isDes[i] = true;        min = A[i];      }    }    int maxdis = 0;    int i = A.length - 1;    int j = A.length - 1;    System.out.println(Arrays.toString(isDes));    while (i >= 0) {      while (isDes[i] == false) {        i--;      }      while (j > i && A[j] <= A[i]) {        j--;      }      if ((j - i) > maxdis) {        maxdis = j - i;      }      i--;    }    return maxdis;}
