Suppose we have a number n. We have to check whether the product of (1*2*...*n) is divisible by (1+2+...+n) or notSo, if the input is like num = 5, then the output will be True as (1*2*3*4*5) = 120 and (1+2+3+4+5) = 15, and 120 is divisible by 15.To solve ... Read More

Suppose we have a number n. We have to check whether the product of odd placed digits and the even placed digits are same or not.So, if the input is like n = 2364, then the output will be True as product of odd placed numbers are 2 * 6 ... Read More

Suppose we have an array nums with all prime numbers. We have to check whether the product of all numbers present in nums is a perfect square or not.So, if the input is like nums = [3, 3, 7, 7], then the output will be True as product of all ... Read More

Suppose we have two coordinates (sx, sy), and (tx, ty), we have to check whether we can move from starting point to ending point or not. Here we can move consists of taking a point (x, y) and transforming it to either (x, x+y) or (x+y, y).So if the inputs ... Read More

Suppose we have two numbers x and y. We have to check whether one of these two numbers is 1's complement of the other or not. We all know the 1's complement of a binary number is flipping all bits from 0 to 1 or 1 to 0.So, if the ... Read More

Suppose we have a number which is either in octal or in decimal form. If this is in octal form check whether it is palindrome or not. If the number in decimal, then convert it to octal then check whether it is palindrome or not.So, if the input is like ... Read More

Suppose we have a number n, and we have another input c. We have to check whether n can be displayed using 7-segment displays or not. Now here is a constraint. We are only allowed to glow at most c number of LEDs.So, if the input is like n = ... Read More

Suppose we have a number n. We have to check whether n is a strong prime or not. As we know a number said to be strong prime when it is a prime number that is greater than the average of nearest prime numbers.So, if the input is like num ... Read More

Suppose we have two numbers x and n. We have to check whether x is divisible by 2^n or not without using arithmetic operators.So, if the input is like x = 32 n = 5, then the output will be True as 32 = 2^5.To solve this, we will follow ... Read More

Suppose we have a number n. We have another two numbers a and b. We have to check whether we can generate a number using a and b that divides n.So, if the input is like n = 115, a = 3, b = 2, then the output will be ... Read More
