Sample Flipkart Grid Coding Questions with Solutions

Problem Statement:

You are working at a package sorting facility for a major e-commerce company. Your task is to design an efficient algorithm that can sort packages based on their weights and ensure that they are loaded onto the delivery trucks in the correct order.

Input:

– You are given a list of packages, each represented by an integer weight. The weights are positive integers, and the list can have duplicates.
– Additionally, you are given the maximum weight capacity of each delivery truck. No truck can carry a package with a weight exceeding this capacity.

Output:

– Your algorithm should sort the packages in a way that they can be efficiently loaded onto the delivery trucks, respecting their weight capacities.

Constraints:

– The number of packages, N, will be an integer in the range 1 ≤ N ≤ 10^5.
– The weight of each package, W, will be an integer in the range 1 ≤ W ≤ 10^3.
– The maximum weight capacity of each truck, C, will be an integer in the range 1 ≤ C ≤ 10^4.

Example:

Input:
packages = {30, 10, 50, 20, 40}

truckCapacity = 60

Output:
{{10, 50}, {20, 40}, {30}}

Solution :

To efficiently sort the packages based on their weights and load them onto the delivery trucks, we can use the “Greedy Algorithm” approach. The idea is to always choose the heaviest package available that can fit within the remaining capacity of the current truck. If no package can fit, start a new truck.

Here’s the step-by-step process:

1. Sort the packages in non-increasing order of their weights.
2. Initialize an empty list of trucks, let’s call it `trucks`.
3. For each package `p` in the sorted list of packages:
– For each truck `t` in `trucks`:
– If the weight of `p` plus the total weight of packages already loaded in `t` is less than or equal to the truck capacity, add `p` to `t` and break the loop.
– If no truck can accommodate `p`, create a new truck `newTruck`, add `p` to `newTruck`, and append `newTruck` to the list of `trucks`.
4. Return the list of trucks after all packages have been processed.

Here’s the C++ code implementation:

#include <bits/stdc++.h>

using namespace std;

vector> sortPackages(vector& packages, int truckCapacity) {
    // Step 1: Sort the packages in non-increasing order of their weights.
    sort(packages.begin(), packages.end(), greater());

    // Step 2: Initialize an empty list of trucks.
    vector> trucks;

    // Step 3: Load packages into trucks based on the Greedy Algorithm approach.
    for (int p : packages) {
        bool loaded = false;
        for (vector& t : trucks) {
            if (t.size() < truckCapacity && t.back() + p <= truckCapacity) {
                t.push_back(p);
                loaded = true;
                break;
            }
        }
        if (!loaded) {
            vector newTruck = {p};
            trucks.push_back(newTruck);
        }
    }

    // Step 4: Return the list of trucks.
    return trucks;
}

int main() {
    vector packages = {30, 10, 50, 20, 40};
    int truckCapacity = 60;

    vector> sortedTrucks = sortPackages(packages, truckCapacity);

    // Output the sorted packages in each truck
    for (const vector& truck : sortedTrucks) {
        cout << "{";
        for (size_t i = 0; i < truck.size(); ++i) {
            cout << truck[i];
            if (i < truck.size() - 1) {
                cout << ", ";
            }
        }
        cout << "}" << endl;
    }

    return 0;
}
