Largest Number– LeetCode Problem

**Problem:**

Given a list of non-negative integers `nums`

, arrange them such that they form the largest number and return it.

Since the result may be very large, so you need to return a string instead of an integer.

**Example 1:**

Input:nums = [10,2]Output:"210"

**Example 2:**

Input:nums = [3,30,34,5,9]Output:"9534330"

**Constraints:**

`1 <= nums.length <= 100`

`0 <= nums[i] <= 10`

Largest Number– LeetCode Solutions

Largest NumberSolution in C++:

class Solution { public: string largestNumber(vector<int>& nums) { string ans; sort(begin(nums), end(nums), [](int a, int b) { return to_string(a) + to_string(b) > to_string(b) + to_string(a); }); for (const int num : nums) ans += to_string(num); return ans[0] == '0' ? "0" : ans; } };

Largest NumberSolution in Java:

class Solution { public String largestNumber(int[] nums) { final String s = Arrays.stream(nums) .mapToObj(String::valueOf) .sorted((a, b) -> (b + a).compareTo(a + b)) .collect(Collectors.joining("")); return s.startsWith("00") ? "0" : s; } }

Largest NumberSolution in Python:

class LargerStrKey(str): def __lt__(x: str, y: str) -> bool: return x + y > y + x class Solution: def largestNumber(self, nums: List[int]) -> str: return ''.join(sorted(map(str, nums), key=LargerStrKey)).lstrip('0') or '0'
