<Codesignal> Is Infinite Process?

Easy

Given integers a and b, determine whether the following pseudocode results in an infinite loop

while a is not equal to b do

       increase a by 1                  

       decrease b by 1                 

Assume that the program is executed on a virtual machine which can store arbitrary long numbers and execute forever.

Example

• For a = 2 and b = 6, the output should be
  isInfiniteProcess(a, b) = false;
• For a = 2 and b = 3, the output should be
  isInfiniteProcess(a, b) = true.

Input/Output

• [execution time limit] 0.5 seconds (c)

• [input] integer a

  Guaranteed constraints:
  0 ≤ a ≤ 20.

• [input] integer b

  Guaranteed constraints:
  0 ≤ b ≤ 20.

• [output] boolean

  • true if the pseudocode will never stop, false otherwise.

[C] Syntax Tips

// Prints help message to the console
// Returns a string
char * helloWorld(char * name) {
    char * answer = malloc(strlen(name) + 8);
    printf("This prints to the console when you Run Tests");
    strcpy(answer, "Hello, ");
    strcat(answer, name);
    return answer;
}

Solution

bool isInfiniteProcess(int a,int b)
{
	return a>b||abs(a-b)%2==1;
}
