Betrothed numbers are a special pair of numbers where the sum of proper divisors of one number equals one more than the other number. These mathematical curiosities demonstrate interesting relationships between divisibility and number theory. Syntax int sumOfProperDivisors(int n); void findBetrothedPairs(int limit); Understanding Betrothed Numbers For example, the pair (48, 75) are betrothed numbers − Proper divisors of 48: {1, 2, 3, 4, 6, 8, 12, 16, 24}, sum = 76 Proper divisors of 75: {1, 3, 5, 15, 25}, sum = 49 Since 76 = 75 + 1 and 49 = ...

The Baum Sweet Sequence is a binary sequence where each term is determined by analyzing the binary representation of a number. If a number n has any block of consecutive zeros with odd length in its binary form, then the nth term is 0, otherwise it is 1. For example, if the number is 4, its binary representation is 100. This has one block of two consecutive zeros (even length), so the 4th term of the Baum Sweet sequence is 1. Syntax int baumSweetTerm(int n); Algorithm The algorithm works as follows − ...

Here we will see how auxiliary space is required for recursive function calls and how it differs from normal function calls in terms of memory usage. Syntax returnType functionName(parameters) { // Base case if (condition) return baseValue; // Recursive case return functionName(modifiedParameters); } Recursive Function Example Consider a recursive factorial function − #include long fact(int n) { if (n == 0 || ...

In C programming, array range queries for elements with frequency same as value is a problem where we need to find how many elements in a given range appear exactly as many times as their value. For example, if element 3 appears 3 times in the range, it contributes to our answer. Syntax int query(int start, int end, int arr[], int n); Algorithm The approach uses frequency counting within the specified range − Begin create frequency map for elements in range [start, end] count ...

Here we will see how to get the area of a decagon inscribed within a circle. A decagon is a 10-sided polygon, and when inscribed in a circle, all vertices of the decagon lie on the circumference of the circle. Given the radius of the circle, we can calculate the area of the inscribed decagon. .circle { fill: none; stroke: #333; stroke-width: 2; } .decagon { fill: rgba(100, 150, 255, 0.3); stroke: #0066cc; stroke-width: 2; } ...
