Good girls and bad boys (5)
On an island, there is this strange pattern - boys always lie while girls always tell the truth. This time, you encounter three children.
The older one says, "My youngest sibling is a girl."
The middle one says, "I have an older brother."
The youngest one says, "We are sisters."
Let 1 denote boys and 0 girls. In order of birth, identify the gender of each child and convert it into a number accordingly. Submit your answer as a string of 3 ones and/or zeroes. For example, if all three are boys, then your answer is 111.
