Check if given number is Emirp Number or not in Python
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 n = 97, then the output will be True as the reverse of 97 is 79 which is another prime.To solve this, we will follow these steps −if num is not prime, thenreturn Falsereverse_num := reverse of numreturn true when reverse_num is prime otherwise falseExampleLet us see the following implementation ...
Read MoreCheck if given number is perfect square in Python
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 as 36 = 6*6.To solve this, we will follow these steps −sq_root := integer part of (square root of n)return true when sq_root^2 is same as n otherwise falseExampleLet us see the following implementation to get better understanding −from math import sqrt def solve(n): sq_root = int(sqrt(n)) return ...
Read MoreCheck if given string can be split into four distinct strings in Python
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 ["hel", "lo", "wor", "ld"]To solve this, we will follow these steps −if size of s >= 10, thenreturn Truefor i in range 1 to size of s - 1, dofor j in range i + 1 to size of s - 1, dofor k in range j + 1 to ...
Read MoreCheck if is possible to get given sum from a given set of elements in Python
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 the output will be True as we can get 26 by using 5 + 5 + 5 + 5 + 3 + 3 + 2To solve this, we will follow these steps −MAX := 1000table := an array of size MAX ad fill with 0Define a function util() . This ...
Read MoreCheck if it is possible to convert one string into another with given constraints in Python
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 sideNeither 'A' nor 'B' can cross each otherSo, if the input is like s = "##AB##B" t = "A###B#B", then the output will be True as in s A can move easily to the left most position, and middle B can move one step to the rightTo solve this, we ...
Read MoreCheck if it is possible to create a palindrome string from given N in Python
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 if the number is 42 the substring "ec" will be printed till 6 (4+2) characters "ececec" then check this is palindrome or not.So, if the input is like n = 43, then the output will be True the string is "ededede" and this is palindrome.To solve this, we will follow ...
Read MoreCheck if it is possible to create a polygon with a given angle in Python
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 know$$Interior Angle(a)=\frac{180\times(n-2)}{n}\begin{bmatrix} n=number of sides of polygon\end{bmatrix}$$ $$¿n=\frac{360}{180-a}$$So if n is integer then this is forming a regular polygon.To solve this, we will follow these steps −sides := 360 /(180 - a)if sides has no fractional part, thenreturn Truereturn FalseExampleLet us see the following implementation to get better understanding −def ...
Read MoreCheck if it is possible to create a polygon with given n sidess in Python
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 three sides and sum of any two sides is larger than the 3rd one. To solve this, we will use this property where length of one side is smaller than the sum of all other sides.To solve this, we will follow these steps −sort the list numsif last element of ...
Read MoreCheck if it is possible to draw a straight line with the given direction cosines in Python
Suppose we have three direction cosines l, m and n in 3-D space, we have to check whether it is possible to draw a straight line with these direction cosines or not.So, if the input is like l = 0.42426 m = 0.56568 n = 0.7071, then the output will be True as this the direction cosines of a vector {3, 4, 5}.To solve this, we will follow some rule asl = cos(a), where a is angle between the straight line and x-axism = cos(b), where b is angle between the straight line and y-axisn = cos(c), where c is ...
Read MoreCheck if it is possible to get back to 12 O-clock only by adding or subtracting given seconds in Python
Suppose we have an array of n different second values. We have to check whether it is possible to start from 12'O clock and go back to 12 by only adding or subtracting the given seconds or not. We can use all given seconds exactly once, we can either add seconds or subtract it.So, if the input is like seconds = [40, 90, 50], then the output will be True as it can add 40 then subtract 90 then again add 50.To solve this, we will follow these steps −size := 2^(length of seconds array)for c in range 0 to ...
