Question

wap in c to find out total number of jumps, he has make to escape from bhopal jail

Answer 1

An activist, of a banned organisation, plans to escape from Bhopal jail. The activist is basically a monkey man and is able to jump across the wall. He practises to cross a wall. He is able to jump 'X' meters, but because of the slippery wall he falls 'Y' meters after each jump. To escape from jail, he has to cross 'N' number of walls, where height of each wall is given in an array.

Write a program to find out the total number of jumps he has make, to escape from the Bhopal jail.

Input Format

Your function will take three arguments:

An integer depicting XAn integer depicting YAn array of N integers having the height of each wall

Constraints

1<= X <=109

1<= Y <=105

Output Format

Your program should return total number of jumps required to escape.

Sample Test Cases

Test case 1

Sample Input

10 1 1 10

Sample Output

1

Explanation

Here, the activist can jump 10 meters high, but slides down by 1 meter. He has 1 wall to jump and the height of the wall is 10 meters. Since he jumps 10 meters in the first attempt he cross the wall easily in the first attempt only.

Test case 2

Sample Input

5 1 2 9 10

Sample Output

5

Explanation

Here, the activist can jump 5 meters high but slides down by 1 meters. He has 2 walls to jump and the walls are 9 and 10 meters high respectively.

While crossing the first wall, the activist takes 2 attempts because during the first attempt he jumps 5 meters but slides down by 1 meters since he didn't cross the wall. In the next attempt he jumps 5 more meters from that position and this time he doesn't slide because he crossed the wall in this attempt because 4+5=9 and 9 meters is the actual height of the wall.

Similarly, while crossing the second wall, the activist takes 3attempts because during his second attempt on this wall, he slides down by 1 meters since 4+5=9 and the height of the wall is 10 meters. During his third attempt, Activist was able to escape from Bhopal Jail.

Answer 2

You should write a program, first of all, you will add input format which will be the following: 

1. An integer depicting X
2. An integer depicting Y
3. And an array of N integers which will be having the height of the wall

following will be the constraints:

1< = X <=109
1< = Y <= 105

and the output format will be the following:
The program should be able to return the total number of jumps which are required to escape.

for example there is a test case
sample input 
10
1
1
10

the sample output will be 
1

the explanation for this is:
that the activist can jump 10 meters high but also slides down by 1 meter and there is a 1 wall which he wants to jump and the height of the wall is also 10 meters. So when he jumps 10 meters in the first attempt he will be able to cross the wall easily in the first attempt.
