Please, i have dead line for today It is considered a finite sir:
u = 1, -2,7,3,2,4,5,6,14,10,8,9,13
Show that from the string u we cannot extract a decreasing substring longer (strictly) than 3 but we can extract an increasing substring longer (strictly) than 4.
b) The date m, n belong. R show that in a series of mn 1 distinct real numbers there is always either a decreasing substring longer than m (at least m 1 terms), or an increasing substring longer than n (so at least n 1 terms)
