PHP solution error "Time limit exceeded"

code:

function solve(array $h, int $limit, array $queries) {
    $res=[];
    for($k=0;$k<count($queries);$k++) {
        $count=0;
        for ($i=$queries[$k][0];$i<=$queries[$k][1];$i++) {
            for ($j=$queries[$k][1];$j>0;$j--) {
                if ($i==$j) break;
                if (abs($h[$i]-$h[$j])>$limit) continue;
                $count++;
            }
        }
        $res[]=$count;
    }
    return $res;
}

#change run oprion to:

$result = solve($h,$k, $queries);

for complete solution in java c++ and c programming search for programs.programmingoneonone.com on google

C++ doesn't include k in the solve function definition... Given code is incomplete.

Can anybody please explain solution?

A brute force solution, good to compare against a routine:

// Complete the solve function below.
static int[] solve(int[] h, int difference, int[][] queries) {
    List<int> ret = new List<int>();
    for(int query=0; query < queries.Length; query++)
    {
        int inicio = queries[query][0];
        int fim = queries[query][1];
        int total = 0;
        for(int iextertno = inicio; iextertno < fim; iextertno++)
        {
            for(int iinterno = iextertno+1; iinterno <= fim; iinterno++)
            {
                int diff = Math.Abs(h[iextertno] - h[iinterno]);
                if(diff <= difference)
                    total++;
            }
        }
        ret.Add(total);
    }
    return ret.ToArray();
}
