Problem $1$:

The arrays price$\_$A$,$ price$\_$B$,$ and price$\_$C given below contain the price in dollars of three stocks over $10$ days.

a$)$ Determine how many days the price of stock A was above both the price of stock $B$ and the price of stock C $.$

b$)$ Determine how many days the price of stock A was above either the price of stock B or the price of stock C$.$

Problem $2$:

The price, in dollars, of a certain stock over a $10-$day period is given in the following array.

prite $=[19,18,22,71,25,19,17,21,27,27]$
