Use ternary when it clearly simplifies if ( (numberOfDisks & 1) == 0 ) smallestDir = 1; else smallestDir = -1; Becomes int smallestDir = (numberOfDisks & 1) == 0 ? 1 : -1 Much shorter and without the smallestDir = repetition. WebbRecursion is the technique of making a function call itself. This technique provides a way to break complicated problems down into simple problems which are easier to solve. Recursion may be a bit difficult to understand. The best way to figure out how it works is to experiment with it. Recursion Example

WebbRecursion Share this article : When we repeat a similar process many times, it is known as Recursion. In Recursion, a function calls itself many times till it hits some base case, making a recursive tree where we pass every child's output is to its parent. Recursion is extremely useful in the cases of tree-based and graph-based problems
