Write three statements to shift the SampleReadings' contents 1 position to the left. The rightmost element after shifting should be assigned -1. Ex: If SampleReadings is [12, 85, 43], then after shifting SampleReadings becomes [85, 43, -1]. function sampleReadings = Shiftvalues(sampleReadings) % sampleReadings: Array containing 3 elements % write three statements to shift the sampleReadings array contents 1 position to the left % Note: The rightmost element should be -1 sampleReadings = sampleReadings: end shiftvalues([12, 85, 43])
