Suppose we have a list of numbers called nums, we have to find the largest product of three unique elements.So, if the input is like nums = [6, 1, 2, 4, -3, -4], then the output will be 72, as we can multiply (- 3) * (-4) * 6 = ... Read More

Suppose we have two lists called nums and multipliers. Now consider an operation where we can remove any number from nums and remove any number from multipliers then multiply them together. We must repeat this operation until one of the lists is empty, we have to find the maximum sum ... Read More

Suppose we have a list with only 0s and 1s called seats. Where seats[i] represents a seat. When it is 1, then it is occupied, otherwise free. There is at least one free seat and at least one occupied seat, we have to find the maximum distance from a free ... Read More

Suppose we have n different nodes. All are distinct. We have to find how many number of ways we can arrange them to form Binary search tree. As we know for binary search trees, the left subtree always hold smaller values and right subtrees hold the greater values.To solve this, ... Read More

Suppose we have outer points of a polygon in clockwise order. We have to check these points are forming a convex polygon or not. A polygon is said to be concave if any one of its interior angle is greater than 180°.From this diagram it is clear that for each ... Read More

Suppose we have a list of numbers called nums. We also have another number x. We have to find all numbers from nums which are less than x by filtering. In we use python there is one filter() method that takes function as argument and filter using this function.So, if ... Read More

Suppose we have a list of n elements; we have to repeat each element in the list n number of times.So, if the input is like nums = [1, 5, 8, 3], then the output will be [1, 1, 1, 1, 5, 5, 5, 5, 8, 8, 8, 8, 3, ... Read More

Suppose we have a number n. We have to find the super digit of this number. The super digit of a single digit number is the digit itself but for multi-digit numbers super digit is the sum of all digits repeatedly until the sum is a single digit number.So, if ... Read More

Suppose we have two arrays called nums1 and nums2. We have to find the number of values that satisfy the following conditions −The elements in nums1 are the factors of the elements which are being selectedThe elements which are selected is a factor of all of the elements of nums2So, ... Read More

Suppose we have outer points of a polygon in clockwise order. We have to check these points are forming a convex hull or not.From this diagram it is clear that for each three consecutive points the interior angle is not more than 180°. So if all angles are not more ... Read More
