**Create Largest Number From a List - Amazon Top Interview Questions**

### Problem Statement :

Given a list of integers nums, rearrange its order to form the largest possible integer and return it as a string. Constraints n ≤ 1,000 where n is the length of nums nums[i] ≤ 1,000 Example 1 Input nums = [10, 7, 76, 415] Output "77641510" Example 2 Input nums = [961, 745, 331, 794, 923] Output "961923794745331" Example 3 Input nums = [45, 14, 70, 67, 95] Output "9570674514" Example 4 Input nums = [70, 5, 94, 18, 78] Output "947870518"

### Solution :

` ````
Solution in C++ :
string solve(vector<int>& _nums) {
// if i have two numbers
// i can try both the ways to combine them
// and select the larger way!
vector<string> nums;
for (const int& num : _nums) {
nums.push_back(to_string(num));
}
// now i just sort these to give the biggest value
sort(nums.begin(), nums.end(), [](const string& a, const string& b) {
string ab = a + b, ba = b + a;
return ab > ba;
});
string res = "";
for (const string& num : nums) {
res += num;
}
return res;
}
```

Solution in Java :
import java.util.*;
import java.util.stream.Collectors;
class Solution {
public String solve(int[] nums) {
return Arrays.stream(nums)
.mapToObj(String::valueOf)
.sorted(Collections.reverseOrder((s1, s2) -> (s1 + s2).compareTo(s2 + s1)))
.collect(Collectors.joining());
}
}

` ````
Solution in Python :
class Number:
def __init__(self, n):
self.n = str(n)
def __lt__(self, other):
return self.n + other.n > other.n + self.n
def __str__(self):
return self.n
class Solution:
def solve(self, nums):
return ''.join(map(str, sorted(map(Number, nums))))

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.

Tieu owns a pizza restaurant and he manages it in his own way. While in a normal restaurant, a customer is served by following the first-come, first-served rule, Tieu simply minimizes the average waiting time of his customers. So he gets to decide who is served first, regardless of how sooner or later a person comes. Different kinds of pizzas take different amounts of time to cook. Also, once h
