// The Signal Stability Analyzer
// In a deep space transmission relay, binary signals are streamed continuously.
//  1 represents a stable signal
//  0 represents a disruption caused by cosmic interference.
// The stability of a transmission session is measured by the longest uninterrupted chain of stable pulses.
// Your task is to determine the maximum  no.of consecutive 1s in the signal log.

// Test Cases
// Input: [1,1,0,1,1,1,0,1]
// Output: 3

// Input: [0,0,0,0]
// Output: 0

// Input: [1,1,1,1,1]
// Output: 5
