# Intuition\nThe problem seems to be about incrementing a given number represented as an array of digits by 1.\n\n# Approach\nThe approach followed in the code is to first join the digits array to create a string representation of the number. Then, this string is converted to a BigInt and incremented by 1. The result is then converted back to a string and split into individual digits.\n\n# Complexity\n- Time complexity:\nJoining the digits array takes O(n) time, where n is the number of digits in the array.\nConverting the string to BigInt takes O(n) time in the worst case.\nConverting the BigInt back to a string takes O(log n) time.\nSplitting the string into individual digits takes O(n) time.\nOverall time complexity is O(n).\n\n- Space complexity:\nThe space used for the string representation (s) is O(n).\nThe space used for the BigInt representation (n) is O(log n).\nThe space used for the final result (output array) is O(n).\nOverall space complexity is O(n + log n) \u2248 O(n) since log n < n for positive integers n.\n\n# Code\n```\n/**\n * @param {number[]} digits\n * @return {number[]}\n */\nvar plusOne = function(digits) {\n  // Convert digits array to a string\n  let s = digits.join("");\n  \n  // Increment the number represented by the string by 1\n  // Using BigInt and 1n to remove the hassle of big integer\n  let n = BigInt(s) + 1n;\n  \n  // Convert the result back to an array of digits\n  return n.toString().split("");\n};\n```
