It's a question of trade offs and compromises. Two engines are easier to deal with than four engines, you'll only have two throttles, two fuel systems, two oil pressure gauges etc etc. OTOH, to get the same power out of two engines as you would have out of four, each engine has to be doubly powerful, and that's a problem too. It'll be bigger, heavier, might run warmer etc. And if you lose one out of two engines during flight, that's a much bigger problem than losing one engine out of four.

Basically you split the list in two, looking at the element in the middle of the list. If the list is in ascending order, and the element you are looking for is SMALLER than the element in the middle of the list, you repeat this procedure for the FIRST half of the list (again, splitting it in two); if it is LARGER, you repeat for the SECOND half of the list.
