waterlevel.c

/*. Southwest monsoon arrived in Andhra Pradesh. The Indian Meteorological Department (IMD)
announced that there will be heavy rains in the upcoming “N” days in Vadlamudi area.
Initially, the Vadlamudi area has ‘zero’ millimeters as its water level. The amount of rain on
the i-th day can be described by an integer “Ri” as follows:
 If Ri > 0, the water level of Vadlamudi area increases by Ri millimeters on the i-th day.
 If Ri = 0, there is no rain on the i-th day. The water level decreases by “X” millimeters on
such a day. Though, if the water level is less than X millimeters before the i-th day, then it
becomes zero.
There will be a high alert in Vadlamudi area if the water level becomes greater
than “G” millimetres on at least one of the “N” days. Decide if there will be a High Alert?
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 three space-separated integers N, X and G.
 The second line contains N space-separated integers R1, R2, R3……….RN
Output: For each test case, print - "YES" if there will be a high alert or "NO" otherwise.*/
