column: The column, counted from the left starting at 0.
row: The row, counted from the top starting at 0.
Output
Return white, black, or an empty string for invalid coordinates.

−10 ≤ column, row ≤ 20. Valid board coordinates are 0 through 7.
उदाहरण
उदाहरण 1
इनपुट:
row = 3
column = 2
अपेक्षित आउटपुट:
expected = "black"इनपुट:
long long row = 3;
long long column = 2;
अपेक्षित आउटपुट:
std::string expected = "black";इनपुट:
long row = 3;
long column = 2;
अपेक्षित आउटपुट:
string expected = "black";व्याख्या
Five steps from the white corner change color an odd number of times.
उदाहरण 2
इनपुट:
row = 0
column = 8

expected = ""इनपुट:
long long row = 0;
long long column = 8;
अपेक्षित आउटपुट:
std::string expected = "";इनपुट:
long row = 0;
long column = 8;
अपेक्षित आउटपुट:
string expected = "";व्याख्या
Column 8 is outside the valid range 0 through 7.
