Ans : Friend function

Given a list of non-negative integers nums, arrange them such that they form the largest number.

Note: 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"Example 3:Input: nums = [1]Output: "1"Example 4:Input: nums = [10]Output: "10"

string largestNumber(vector<int>& nums) {sort(nums.begin(),nums.end(),[](int a,int b){string c=to_string(a);string d=to_string(b);return (c+d)>(d+c);});string p="";for(int i=0;i<nums.size();i++)p+=to_string(nums[i]);int i=0;while(i<p.size() && p[i]=='0')i++;if(i==p.size())return "0";return p.substr(i);}
