Nested Object Flattening\n\n**Problem:**  \nWrite a function to flatten a deeply nested JavaScript object into a single-level object with dot-separated keys.\n\n### Example\n\n```ts\nInput:\n{\n  a: {\n    b: {\n      c: 5\n    }\n  },\n  d: 10\n}\n\nOutput:\n{\n  \"a.b.c\": 5,\n  \"d\": 10\n}\n```\n\n## 2. Find Missing Number\n\n**Problem:**  \nYou are given an array of `n` unique integers where each integer is between `1` and `n+1` (inclusive), but one number is missing. Return the missing number.  \nYour solution should run in **O(n)** time and **O(1)** space.\n\n---\n\n### Example 1\n\n**Input:**  \n`[1, 2, 4, 5, 6]`\n\n**Expected Output:**  \n`3`\n\n---\n\n### Example 2\n\n**Input:**  \n`[2, 3, 4, 5, 6, 7, 8]`\n\n**Expected Output:**  \n`1`\n\n## 3. String Permutation Validator\n\n**Problem:**  \nWrite a function that checks whether two strings are permutations of each other.  \nTwo strings are permutations if they contain the same characters with the same frequency, in any order.\n\n---\n\n### Example 1\n\n**Input:**  \n`\"listen\", \"silent\"`\n\n**Expected Output:**  \n`true`\n\n---\n\n### Example 2\n\n**Input:**  \n`\"hello\", \"world\"`\n\n**Expected Output:**  \n`false`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbytangle%2Fktest211","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbytangle%2Fktest211","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbytangle%2Fktest211/lists"}
