WebFeb 21, 2024 · In Java, a recursive function is a function that calls itself, typically with modified input parameters, until a specific termination condition is met. Recursion is useful for solving problems that have a recursive structure, such as computing the factorial of a number or traversing a tree data structure WebAug 3, 2024 · The step by step backtracking is shown as follows: Start The red cross marks the positions which are under attack from a queen. Whenever we reach a state where we have a queen to place but all the positions in the rows are under attack, we backtrack. This is not the only possible solution to the problem.
