<Codesignal> chessBoardCellColor

Easy

Given two cells on the standard chess board, determine whether they have the same color or not.

Example

• For cell1 = "A1" and cell2 = "C3", the output should be
  chessBoardCellColor(cell1, cell2) = true.

  

• For cell1 = "A1" and cell2 = "H3", the output should be
  chessBoardCellColor(cell1, cell2) = false.

  

Input/Output

• [execution time limit] 0.5 seconds (c)

• [input] string cell1

  Guaranteed constraints:
  cell1.length = 2,
  'A' ≤ cell1[0] ≤ 'H',
  1 ≤ cell1[1] ≤ 8.

• [input] string cell2

  Guaranteed constraints:
  cell2.length = 2,
  'A' ≤ cell2[0] ≤ 'H',
  1 ≤ cell2[1] ≤ 8.

• [output] boolean

  • true if both cells have the same color, 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 chessBoardCellColor(char *cell1,char *cell2)
{
	return abs(cell1[0]-cell2[0])%2==abs(cell1[1]-cell2[1])%2;
}
