A city has \( n \) middle schools, and the \( i \)-th school sends \( C_{i} \) students to the stadium to watch a game. It is known that \( 0 \leq C_{i} \leq 39 \) for \( i = 1, 2, \cdots, n \), and \( C_{1} + C_{2} + \cdots + C_{n} = 1990 \). Each row of seats in the stands has 199 seats. It is required that students from the same school must sit in the same row. What is the minimum number of rows that need to be arranged to ensure that all students can be seated as required?
