@ncbaoyanan it's like this.

public boolean find123Pattern(int[] nums) {

int v3_c = Integer.MIN_VALUE;

int v2 = Integer.MIN_VALUE;

for (int i = nums.length - 1; i >= 0; i--) {

if (nums[i] < v2) {

return true;

}

if (nums[i] < v3_c) {

v2 = nums[i];

} else {

v3_c = nums[i];

}

}

return false;

}
