Available question text
Given a start IPv4 address and a number of consecutive addresses, produce the minimal list of CIDR blocks that exactly cover that range. The key challenge is using 32-bit alignment and powers-of-two block sizes (via bitwise/trailing-zero logic) to greedily choose the largest aligned CIDR at each step.
