Number of Questions: Typically 2 coding problems.

Difficulty Level: Easy - Medium.

Languages Allowed: C, C++, Java, Python.

Here, are the rules to be followed while answering accenture coding questions:

• You must write the entire program without any pre-existing code.
• You need to write the code for the given problem statements. Once done, run the program to see the output.
•  If there are any errors in your code, they will be displayed to help you debug.
• To pass this section, you typically need one clear output and one partial output.

Accenture often uses a variety of coding challenges to test your problem-solving skills. Here’s a list of 10 Accenture coding questions:

1. In a race, each participant's finish time is recorded. You need to find out who finished first and how long it took them. Additionally, you need to find the average finish time of all participants.

Input Format

• A list of floating-point numbers representing finish times.

Output Format

• Two floating-point numbers: the first-place time and the average time.

Example

Input: [12.5, 10.0, 11.2, 13.3]
Output: (10.0, 11.5)

Python

def race_results(times):
    if not times:
        return None, 0

    first_place_time = min(times)
    average_time = sum(times) / len(times)
    return first_place_time, average_time

# Example usage
print(race_results([12.5, 10.0, 11.2, 13.3]))  # Output: (10.0, 11.5)

Java

public class Main {
    public static double[] raceResults(double[] times) {
        if (times.length == 0) return new double[]{-1, 0};

        double firstPlaceTime = times[0];
        double totalTime = 0;
        
        for (double time : times) {
            if (time < firstPlaceTime) firstPlaceTime = time;
            totalTime += time;
        }
        
        double averageTime = totalTime / times.length;
        return new double[]{firstPlaceTime, averageTime};
    }

    public static void main(String[] args) {
        double[] results = raceResults(new double[]{12.5, 10.0, 11.2, 13.3});
        System.out.println("First Place Time: " + results[0] + ", Average Time: " + results[1]);
    }
}

C

#include <stdio.h>

void raceResults(double times[], int size, double* firstPlace, double* average) {
    if (size == 0) {
        *firstPlace = -1;
        *average = 0;
        return;
    }

    *firstPlace = times[0];
    double totalTime = 0;

    for (int i = 0; i < size; i++) {
        if (times[i] < *firstPlace) *firstPlace = times[i];
        totalTime += times[i];
    }

    *average = totalTime / size;
    }

int main() {
    double times[] = {12.5, 10.0, 11.2, 13.3};
    double firstPlace, average;
    raceResults(times, 4, &firstPlace, &average);

To excel in the Accenture coding assessment, consider these helpful tips:

• Use coding platforms like LeetCode, HackerRank, or CodeSignal to work on problems similar to Accenture's previous year's coding questions.
• Ensure you have a solid understanding of data structures and algorithms, as many questions will test these skills.
• Focus on writing code that is easy to read and understand. Use clear names for variables and add comments when necessary.
• Think about how to make your code faster and use less memory. Understanding time and space complexity is crucial.
• Practice with friends or use online platforms to simulate real interview conditions, helping you get comfortable under pressure.

In conclusion, preparing for Accenture coding questions requires a mix of theoretical knowledge and practical coding skills. By knowing the types of questions commonly asked and practicing consistently, you can increase your chances of doing well in the coding rounds.
