Type of QuestionsDescriptions
LogicalThere may be some logical errors in the code snippet, which the candidate must
be able to find and resolve
CompilationThere may be some compilation error in the code,
the candidate must be able to find those syntactical errors and resolve them
Code ReuseThe candidate must try to reduce the length of the code,
without changing the functionality of the code.

Some more details –

Automata Fix is an assessment solution to check for a computer programmer’s ability to correct an erroneous code and fix it. The test provides a set of programs to the candidate, where they have to either correct them or right new functionality based on the given functions and code. It tests the candidate’s skill of being able to understand code written by someone else, be able to find bugs and also use the code to implement new functionality.

Question : 1

Check for syntax error/ logical error and correct the error to get the desired output.

The function sortString  modifies the input list by sorting its elements depending upon the length of the array, i.e; if the length of the array is even, then the elements are arranged in the ascending order, and if the length of the array is odd, then the elements are arranged in the descending order 

The function sortString accepts two arguments – len representing the length of the string, and arr a list of characters, representing the input list respectively.

The function sortString compiles successfully but fails to get the desired results for some test cases due to logical errors. Your task is to fix the code, so that it passess all the test cases

 

Incorrect Code

void sortArray(int len, int *arr)
{
    int i, max, location, temp, j,k;
    if(len/2 == 0)//error in this line
    {
    for(i=0;i<len;i++)
    {
        max=arr[i];
        location = i;
        for(j=i;j<len;j++)
        if(max<arr[j])//error in this line
        {
            max=arr[j];
            location = j;
            
        }
        temp=arr[i];
        arr[i]=arr[location];
        arr[location]=temp;
    }
    }
    else
    {
        for(i=0;i<len;i++)
    {
        max=arr[i];
        location = i;
        for(j=i;j<len;j++) if(max>arr[j])//error in this line
        {
            max=arr[j];
            location = j;
            
        }
        temp=arr[i];
        arr[i]=arr[location];
        arr[location]=temp;
    }
    }
}
Correct Code
void sortArray(int len, int *arr)
{
int i, max, location, temp, j,k;
if(len%2 == 0)
{
for(i=0;i<len;i++)
{
max=arr[i];
location = i;
for(j=i;j<len;j++)
if(max>arr[j])
{
max=arr[j];
location = j;

}
temp=arr[i];
arr[i]=arr[location];
arr[location]=temp;
}
}
else
{
for(i=0;i<len;i++)
{
max=arr[i];
location = i;
for(j=i;j<len;j++)
if(max<arr[j])
{
max=arr[j];
location = j;

}
temp=arr[i];
arr[i]=arr[location];
arr[location]=temp;
}
}
}

Question : 2

Check for syntax error/ logical error and correct the error to get the desired output.

The function maxReplace print space separated integers representing the input list after replacing all the elements of the input list with the sum of all the element of the input list.

The function maxReplace accepts two arguments – size  an integer representing the size of the input list and inputList, a list of integers representing the input list respectively.

The function maxReplace compiles unsuccessfully due to compilation errors. Your task is to fix the code so that it passes all the test cases.

 

void maxReplace(int size, int *inputList)
{
    int i,sum=0;
    for(i=0;i<size;i++)
    {
         sum += inputList[i];
    }
        for(i=0;i<size;i++)
        {
            sum = inputList[i];//error in this line
        }
    for(i=0;i<size;i++)
    {
        printf("%d ",inputList[i]);
    }
}
Corrected Code
void maxReplace(int size, int *inputList)
{
int i,sum=0;
for(i=0;i<size;i++)
{
sum += inputList[i];
}
for(i=0;i<size;i++)
{
inputList[i]=sum;
}
for(i=0;i<size;i++)
{
printf("%d ",inputList[i]);
}
}

Question : 3

Check for syntax error/ logical error and correct the error to get the desired output.

The function replaceElements is modifying the input list in such a way – if the sum of all the elements of the input list is odd, then all the elements of the input list are supposed to be replaced by 1s, and in case if the sum of all the elements of the input list  is even, then the elements should be replaced by 0s.

For example, given the input list [1,2,3,4,5], the function will modify the input list like [1, 1, 1, 1, 1] 

The function replaceElements  accepts two arguments – size an integer representing the size of the given input list and arr, a list of integers representing the input list.

The function replaceElements compiles successfully but fails to get the desired result for some test cases due to incorrect implementation of the function. Your task is to fix the code so that it passes all the test cases

 

void replaceElements(int size, int *arr)
{
    int i,j;
    int sum=0;
    for (i=0;i<size;i++)
    {
        sum+=arr[i];
    }
    if(size % 2 == 0)//error in this line
    {
        i=0;
        while(i<size)
        {
            arr[i] = 0;
            i += 1;
            
        }
    }
    else
    {
        j=1;
        while(j<size)
        {
            arr[j]=1;
            j+=1;
        }
    }

Corrected Code

void replaceElements(int size, int *arr)
{
int i,j;
int sum=0;
for (i=0;i<size;i++)
{
sum+=arr[i];
}
if(sum % 2 == 0)
{
i=0;
while(i<size)
{
arr[i] = 0;
i += 1;

}
}
else
{
j=1;
while(j<size)
{
arr[j]=1;
j+=1;
}
}
