try considering this test case:

3 74 51
75 2
77 7
80 9


See,if after correcting this it still gives a wrong answer....

My approach would be to find the value of [mid] month and [mid -1] month ..

if sum of [mid] month is greater than required and sum of [mid-1] month is less then required  than mid is the answer ..otherwise continue binary search...
