Determine Stability Risk Problem Description Amazon is launching a revolutionary resource optimization feature that incorporates an advanced diagnostic program, adept at identifying and evaluating potential system vulnerabilities. This framework manages `n` active services, each with a unique Service Identifier (SID). The diagnostic program evaluates the overall system stability of the infrastructure using a specialized algorithm. * The algorithm analyzes contiguous subarrays of Service Identifiers (SIDs) represented by the array `service_id`. * For each subarray, it calculates the sum of the SIDs and divides this sum by a constant `modulus`. * The remainder obtained from this division is compared to the number of services in the subarray. * A subarray is flagged if the remainder equals the number of services within it and is considered as vulnerable. * The overall system stability risk is determined by the total count of such flagged subarrays. Formally, given an array `service_id` of
