coupon.c

/*Siva is very busy with work and wants to order food from Zomato. He wants to order one time
today, and buy three items costing X1, X2 and X3 rupees. He'll also order once tomorrow, where
he'll buy three items costing Y1, Y2 and Y3 rupees. There is an additional delivery charge of
rupees “A” on each order. He also notices that there is a coupon on sale, which costs
rupees “C”. If he buys that coupon, the delivery charges on any day and on an order of ₹150 or
more shall be waived (that is, the “A” rupees will not be added, if the sum of the costs of the
items is ≥150). So Siva is ordering three items together on each day, so the delivery charge
apply only once each day. Also, it's only needed to buy that coupon once to benefit the delivery
fee waiver on both days. Should Siva go ahead and buy the coupon?
Note that Shiva will buy the coupon only if it costs him strictly less than what it costs him
without the coupon, in total.
Input:
 The first line of the input contains a single integer T, denoting the number of test cases.
 The first line of each test case contains two space-separated integers “A” and “C”, denoting
the delivery charge and price of the coupon.
 The second line of each test case contains three space-separated integers X1, X2 and X3,
denoting the prices of the food items to order on Day 1.
 The third line of each test case contains three space-separated integers Y1, Y2 and Y3, denoting
the prices of the food items to order on Day 2.
Output: For each test case, output YES if Siva should buy the coupon, or NO otherwise.*/
