# coding assessment ibm with code examples

Coding assessments are an essential part of the hiring process for many companies, including IBM. These assessments are designed to test a candidate's technical skills, knowledge of specific programming languages, and problem-solving abilities. In this article, we will discuss IBM's coding assessments, what to expect during the assessment, and provide code examples to help you prepare.

IBM's coding assessments are typically timed and are conducted online. The assessments are designed to test a candidate's knowledge of specific programming languages and their ability to solve problems in a limited amount of time. The assessments can consist of multiple-choice questions, coding challenges, and coding projects.

The types of coding challenges you can expect during an IBM coding assessment include:

• Algorithm challenges, where you are asked to write code to solve a specific problem
• Data structure challenges, where you are asked to implement a specific data structure and perform certain operations on it
• Coding projects, where you are given a problem statement and asked to write code to solve the problem.

One of the most important things to remember when preparing for an IBM coding assessment is to practice coding and problem-solving. Start by reviewing basic concepts and algorithms, and then move on to more advanced topics. Additionally, you should also practice writing code in the programming language that you expect to be tested on.

Here are a few examples of coding challenges you may encounter during an IBM coding assessment:

• Algorithm Challenge: Write a function that takes an array of integers as input and returns the second largest number in the array.
```def second_largest(arr):
largest = max(arr)
arr.remove(largest)
second_largest = max(arr)
return second_largest

print(second_largest([1, 2, 3, 4, 5])) # 4
print(second_largest([5, 4, 3, 2, 1])) # 4
```
• Data Structure Challenge: Implement a stack data structure and write a function that takes a string as input and checks if the string has balanced parentheses.
```class Stack:
def __init__(self):
self.items = []

def is_empty(self):
return len(self.items) == 0

def push(self, item):
self.items.append(item)

def pop(self):
if not self.is_empty():
return self.items.pop()

def peek(self):
if not self.is_empty():
return self.items[-1]

def is_balanced(string):
stack = Stack()
for char in string:
if char == '(' or char == '{' or char == '[':
stack.push(char)
elif char == ')' or char == '}' or char == ']':
if stack.is_empty():
return False
top = stack.pop()
if (top == '(' and char != ')') or (top == '{' and char != '}') or (top == '[' and char != ']'):
return False
if stack.is_empty():
return True
else:
return False

print(is_balanced("(())")) # True
print(is_balanced("({[()]})") # True
print(is_balanced("(}")) # False
```
• Coding Project: Write a program that takes a list of
Coding projects are a more advanced type of challenge that you may encounter during an IBM coding assessment. These projects will typically involve writing a program to solve a real-world problem, such as a web scraping tool or a data analysis tool. The problem statement for a coding project will usually provide detailed instructions on what the program should do and what inputs and outputs are expected.

When preparing for a coding project, it's important to practice writing code that solves real-world problems. This could involve working on open-source projects, contributing to hackathons or coding competitions, or completing coding challenges on websites like HackerRank or LeetCode. Additionally, it's also important to understand how to write efficient and maintainable code. This includes understanding how to write clean and readable code, how to handle errors and exceptions, and how to write unit tests.

Another important aspect of coding assessments is the ability to explain your solution to the problem. During the assessment, you will likely be asked to explain your thought process and the steps you took to solve the problem. It is important to practice explaining your code and thought process in a clear and concise manner.

Overall, preparing for an IBM coding assessment requires a combination of knowledge and practice. Reviewing basic concepts and algorithms, practicing coding, and working on real-world problems will help to build your technical skills. Additionally, practice writing efficient and maintainable code, and explaining your thought process will help you to perform well during the assessment.

In summary, IBM coding assessments are designed to test the candidate's technical skills, problem-solving abilities and knowledge of specific programming languages. These assessments can consist of multiple-choice questions, coding challenges and coding projects. To prepare for such assessments, candidates should practice coding and problem-solving, review basic concepts and algorithms, practice writing efficient and maintainable code and practice explaining their thought process.
