# Intuition\nThe task is to subtract the sum of the digits of a number from the product of the digits. To do this, we\'ll convert the number into its string representation to easily iterate through each digit.\n\n# Approach\n1. Convert the number n into a string so we can iterate over each digit.\n2. Initialize two variables, sum and product, to store the sum and product of the digits, respectively. Start with sum = 0 and product = 1.\n3. Loop through each character (digit) in the string:\n    * Convert the character back to a number and add it to sum.\n    * Multiply the product by this number.\n4. After the loop, return the difference between product and sum.\n\n# Complexity\n* Time complexity: \n    * The time complexity is O(d) where d is the number of digits in the number n. This is because we iterate through each digit exactly once.\n* Space complexity: \n    * The space complexity is O(1) since we are only using a fixed amount of extra space (for variables sum, product, and the string conversion).\n\n# Code\n```javascript []\n/**\n * @param {number} n\n * @return {number}\n */\nvar subtractProductAndSum = function(n) {\n    let num = n.toString()\n    let sum =0;\n    let product = 1;\n    for(let x of num){\n        sum += Number(x)\n        product *= Number(x)\n    }\n    return product - sum;\n};\n```
