# Absolute Difference of two consecutive array integers…[Cprogm] FTC

Rakesh has given an array of integers and you need to find out if the absolute difference of values of any two consecutive array integers is at-most D.

``````Input:
First line of input contains an integer T, denoting the number of test cases.

First line of each test case contains two integers N and D, denoting the size of the array and value of D respectively.

Second line of each test case contains N integers, which are separated by one space and are the integers for the array.

Output:
Print YES if the absolute difference between any two consecutive integer is at-most D, otherwise print NO``````
```#include <stdio.h>
#include <stdlib.h>
int main()
{
int j=0,t,i,n,k;
scanf("%d",&t);
while(j<t)
{
scanf("%d %d",&n,&k);
int integers[n];
int flag=0;
for(i=0;i<n;i++)
scanf("%d",&integers[i]);
for(i=0;i<n;i++)
if(abs(integers[i]-integers[i+1])<=k)
flag++;
if(flag==(n-1))
printf("\nYES");
else
printf("\nNO");
j++;
}

return 0;
}```

INPUT_1:
