Suppose we have two radius values r1 and r2 of two concentric circles. We have another input coordinate coord and a radius value r. We have to check whether the circle whose center is placed at coord and it fits inside the boundary of two given concentric circles.So, if the ... Read More

Suppose we have an array nums and another value k. We have to check whether it is possible to reach the end of the array by performing these operations or not Operation: Traverse nums and, if any non-prime value is there then decrement the value of k by 1. Now ... Read More

Suppose we have a number n. We have to check whether n is an ore number or not. As we know an ore number is a number whose divisors have an integer harmonic value.So, if the input is like 28, then the output will be True as there are six ... Read More

Suppose we have a number num. We have to check whether num is consists of only 0s and 1s or not.So, if the input is like num = 101101, then the output will be True.To solve this, we will follow these steps −digits_set := a new set with all elements ... Read More

Suppose we have an array nums, we have to check whether this array is containing all of the divisors of some integer or not.So, if the input is like nums = [1, 2, 3, 4, 6, 8, 12, 24], then the output will be True as these are the divisors ... Read More

Suppose we have an array nums and a value k, we have to check whether the elements in nums can be made 0 by performing the following operation exactly k number of times or not.Operation: The smallest element from the nums will be subtracted from all of the non-zero values ... Read More

Suppose we have a string s with lowercase, uppercase, numeric and special characters. We have to check whether frequency of any one of character is more than the half of length of string or not.So, if the input is like s = "CC*Ca5&CC", then the output will be True as ... Read More

Suppose we have a number num we have to check whether is balanced or not. A number is balanced when frequencies of all digits are same or not.So, if the input is like num = 562256, then the output will be True as frequency of each digit is 2.To solve ... Read More

Suppose we have an array called digits that contains only digits. We have to find the minimum possible number from the given digits and then check whether the numbers by taking first and last digits of the generated number are prime or not. We will print the number itself and ... Read More

Suppose we have a stack of numbers; we have to check whether values in the stack are pairwise consecutive or not. These pairs can be increasing or decreasing. If the stack has an odd number of values, the top element is left out of a pair. And we should retain ... Read More
