Create an array with these numbers: $2\mathrm{.}4,1\mathrm{.}3,2\mathrm{.}4,4\mathrm{.}5,6\mathrm{.}7,$

$4\mathrm{.}5,9\mathrm{.}0$

Use the find function to find the position of $4\mathrm{.}5$ in the array.

Use the find$\_$if function to find the position of the first element that

is less than $2.$

Use the find$\_$end function to find the sequence position $\{2\mathrm{.}4,4\mathrm{.}5\}$ in

the array.

Use the find$\_$first$\_$of function to find the position of the first

common element in the array and a list with these values

$\{34,55,2\mathrm{.}4,4\mathrm{.}5\}$
