The function should return True if there is no pair of consecutive values ts$[$i$]$ and ts$[$i$+1]$ in the time series such that $($ts$[$i$+1]$ ts$[$i$])>$ delta, or False otherwise. You can assume that the input arguments are correctly formatted. For example$-$ you are given a time series in the form of a list of integers e$.$g$.,$ the daily Covid case count leckietopia $=[58,54,54,52,54,50,47]$ The time series in leckietopia has a small increase from $52$ to $54$ However, if we tolerate noise of at least $2$ in the differences between successive readings, then this time series could be considered to be consistently falling or steady, i$.$e$.,$ 'non$-$increasing'.
