We have Two arrays ans[0,1,----(n-1)] and rem[0,1,----(n-1)]. We have to find minimum value of x such that x%ans[0] = rem[0], x%ans[1] = rem[1], and so on. Chinese Remainder Theorem states that there always exist x which satisfy the given congruenc...
The major approach to finding the prime number is running the loop from 2 to n and check whether it divides the number or not. The complexity of that solution is O(n). In this article, We will be discussing how to find the prime number in O(sqrt(n))c...
In this equation, we make an equation in terms of x and y and we input a,b, and c in which a is the coefficient of x, b is the coefficient of y and c is a term that is equal to it ax+by = c This helps us to determine whether there is any possible so...
