这里可以采用值-下标映射的方法,即把所有元素移动到其值减1的对应的下标的位置上,移动完成后,下标和值不匹配的元素即为缺失的number。例如输入[4,3,2,7,8,2,3,1], [4, 3, 2, 7, 8, 2, 3, 1] # 初始状态 [7, 3, 2,4, 8, 2, 3, 1] #4和下标为4-1的元素互换 [3, 3, 2, 4, 8...

也可以采用First Missing Positive中swap的方法,把nums[i] swap到 index = nums[i]的位置上. 第二遍扫描时如果出现了i != nums[i]时,就是nums[i]是duplicate. Time Complexity: O(nums.length). Space: O(1). AC Java: 1classSolution {2publicintfindDuplicate(int[] nums) {3for(inti = 0; i<...

In the first step, you need to build a word Map by reading the contents of a Text File. This Map should contain words as a key and their count as value. Once you have this Map ready, you can simply sort the Map based upon values. Btw, If you don't know how to sort a Map ...
