[C# Operators] Sequence of Operators

// We are given integer number n, value v (v=0 or 1) and a position p.
// Write a sequence of operators that modifies n to hold the value v at the position p from the binary representation of n.
// Example: n = 5 (00000101), p=3, v=1 --> 13 (00001101)
// n = 5 (00000101), p=2, v=0 --> 1 (00000001)
