I work at Amazon for 2 years and had my telephonic interview today. This was the question I was asked : \n\nThere is an 2-d array filled with \'T\' and \'L\'. Cell with \'T\' represents land while cell with \'L\' represents water. If there is a land locked water then it will counted as land area. Land locked means it is surrounded by land for all 4 sides. Find the area of largest connected land. \n\nEdge cases : For example let\'s assume following array :\n\nTTTF\nTFTT\nTTTF\nFFFF\n\nArea of largest connected land is 10. Cell with co-ordinates 1,1 is counted in land area as it is land locked.\n\nAnother example :\n\nTTTT\nTFFF\n\nArea for this is 5. Cells with water are not land locked here.\n\nHope this post will help you!
