Hi Nipun,In this question you have to take input of numbers as long as the sum of numbers become negative and print those numbers which are giving the positive sum.

1 3 7 19-this are values of c1,c2,c3 and c4
2 3-this line tells us that he will use 2 rickshaws and 3 cabs
2 5-this line tells the number of times ramu is going to use of rickshaw0 and rickshaw 1 respectively
4 4 4-this line tells the number of times ramu is going to use of cab0, cab1 and cab2 respectively
Dry run for the given input:
So for riding rick0 one way is that he purchase ticket c1 twice so total cost will be 2 there is one more way that he can chose ticket c2 but as c2 costs rs 3 so he will select option 1 where he has to pay 2 rs.
Now for rick1 by first option he has to pay 5*1 rs and second option is that he can purchase ticket c2 that costs 3 rs so he will purchase ticket c2(as 3 is less than 5)…now compare 5 rs with cost of c3 as 5 rs is less than 7 so we will select to pay 5 rs.
So total cost of riding the rickshaws is 5 rs
Now do the same thing for cabs…and suppose total cost of riding cabs is say ‘x’…then total rides will cost x+5…compare this value with c4…return their min as your ans…
