+ * Checks whether the given number is a power of four or not.
+ *
+ * A number is considered a power of four if and only if there is a single '1' bit in its binary representation,
+ * and that '1' bit is at the first position, followed by an even number of '0' bits.
+ *
+ * @param {number} n - The input number to check.
+ * @returns {boolean} True if the number is a power of four, false otherwise.
+ *
+ * @example
+ * const result = isPowerOfFour(16); // Returns true (16 is 4^2)
+ * const result2 = isPowerOfFour(5);  // Returns false (5 is not a power of four)
