一、Next Greater Element I问题描述:问题求解:本题只需要将nums2中元素的下一个更大的数通过map保存下来,然后再遍历一遍nums1即可。1 2 3 4 5 6 7 8 9 10 11 12 13 public int[] nextGreaterElement(int[] nums1, int[] nums2) { int[] res = new int[nums1.length]; Map<Integer, Integer>...
Explanation: For number 4 in the first array, you cannot find the next greater number for it in the second array, so output -1. For number 1 in the first array, the next greater number for it in the second array is 3. For number 2 in the first array, there is no next greater n...

Given a circular array (the next element of the last element is the first element of the array), print the Next Greater Number for every element. The Next Greater Number of a number x is the first greater number to its traversing-order next in the array, which means you could search ci...
