Suppose we have an array nums that contain the size of n sides. We have to check whether we can form a polygon with all of the given sides or not.So, if the input is like nums = [3, 4, 5], then the output will be True because there are ... Read More

Suppose we have an angle a. We have to check whether we can make a regular polygon where all angles are same as a or not.So, if the input is like a = 120, then the output will be True the pentagon has all angles same as 120°. As we ... Read More

Suppose we have a number n. We have to check whether we can create an alphabetical lowercase string from that number and check whether the string is palindrome or not. Here we will take only characters from a to j, [a = 0, b = 1... j = 9]. So ... Read More

Suppose we have two strings s and t with only three characters 'A', 'B' and '#'. We have to check whether it is possible to convert s into t by performing these operations on s.'A' can move only to the left hand side'B' can move only to the right hand ... Read More

Suppose we have an array called nums and another value sum. We have to check whether it is possible to get sum by adding elements present in nums, we may pick a single element multiple times.So, if the input is like nums = [2, 3, 5] sum = 28, then ... Read More

Suppose we have a string s, we have to check whether we can split it into four sub-strings such that each of them are non-empty and unique.So, if the input is like s = "helloworld", then the output will be True as one of the possible set of sub-strings are ... Read More

Suppose we have a number n. We have to check whether the number n is perfect square or not. A number is said to be a perfect square number when its square root is an integer.So, if the input is like n = 36, then the output will be True ... Read More

Suppose we have a number n. We have to check whether n is an Emirp number or not. We all know Emirp number is (letters of prime in backward direction) is a prime number that results in a different prime when its digits are reversed.So, if the input is like ... Read More

Suppose we a number n and another value x, we have to check whether it is a power of x or not, where x is a number power of 2.So, if the input is like n = 32768 x = 32, then the output will be True as n is ... Read More

Suppose we have a list of four sides, we have to check whether these four sides are forming a rectangle or not.So, if the input is like sides = [10, 30, 30, 10], then the output will be True as there are pair of sides 10 and 30.To solve this, ... Read More
