这里每一个数在我们做映射算法的时候,会依据这个数找到一个数组的位置,所以不能用其他标记。 我的python代码: 1classSolution(object):2deffindDuplicates(self, nums):3"""4:type nums: List[int]5:rtype: List[int]6"""7res =[]8foriinnums:9ifnums[abs(i)-1] >0:10nums[abs(i)-1] *= -11...
Here, both“Math”and“Science”are key, but these are the values in the original dictionary, so they are duplicates. Find Duplicate Values in Dictionary Python using values() You can use the for-loop to iterate over the dictionary with thevalues()method to get all the dictionary values, a...
