Given a string s and a number of rows numRows, arrange the string in an L-shaped pattern from top to bottom, left to right. Then, read the characters row by row from left to right to produce a new string. Implement this transformation with the function signature: transform(s: string, numRows: number) => string For example, with input string ...
