**Grading Students**

### Problem Statement :

HackerLand University has the following grading policy: 1. Every student receives a grade in the inclusive range from 1 to 100. 2. Any grade less than 30 is a failing grade. Sam is a professor at the university and likes to round each student's grade according to these rules: 1.If the difference between the grade and the next multiple of 5 is less than 3 , round up to the next multiple of 5. 2.If the value of grade is less than 38 , no rounding occurs as the result will still be a failing grade. Examples 1. grade = 84 round to85 (85 - 84 is less than 3) 2. grade = 29 do not round (result is less than 40) 3. grade = do not round (60 - 57 is 3 or higher) Given the initial value of grade for each of Sam's n students, write code to automate the rounding process. Function Description Complete the function gradingStudents in the editor below. gradingStudents has the following parameter(s): int grades[n]: the grades before rounding Returns int[n]: the grades after rounding as appropriate Input Format The first line contains a single integer,n , the number of students. Each line i of the n subsequent lines contains a single integer, grades[i]. Constraints 1<= n < =60 0 <= grades[i] <= 100

Solution in C :
In C :
int* gradingStudents(int grades_count, int* grades, int* result_count) {
static int my_grades[10];
for(int i = 0; i< grades_count ; i++)
{
if(grades[i] < 38) my_grades[i] = grades[i];
else if((grades[i] % 5)==0) my_grades[i] = grades[i];
else
{
int num = grades[i];
int num2 = grades[i];
while((num % 5) !=0)
{
num = num +1;
}
if((num-num2) < 3) my_grades[i] = num;
else my_grades[i] = num2;
}
}
*result_count = grades_count;
return my_grades;
}

View Solution →## Tree: Huffman Decoding

Huffman coding assigns variable length codewords to fixed length input characters based on their frequencies. More frequent characters are assigned shorter codewords and less frequent characters are assigned longer codewords. All edges along the path to a character contain a code digit. If they are on the left side of the tree, they will be a 0 (zero). If on the right, they'll be a 1 (one). Only t
