Problem:
Score: 300 points

Problem Statement

M-kun is a student in Aoki High School, where a year is divided into N terms.

There is an exam at the end of each term. According to the scores in those exams, a student is given a grade for each term, as follows:

For the first through (K-1)-th terms: not given.

For each of the K-th through N-th terms: the multiplication of the scores in the last K exams, including the exam in the graded term.

M-kun scored A_i in the exam at the end of the i-th term.

For each i such that K+1 \leq i \leq N, determine whether his grade for the i-th term is strictly greater than the grade for the (i-1)-th term.

Constraints

2 \leq N \leq 200000

1 \leq K \leq N-1

1 \leq A_i \leq 10^{9}

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N K
A_1 A_2 A_3 \ldots A_N

Output

Print the answer in N-K lines.

The i-th line should contain Yes if the grade for the (K+i)-th term is greater than the grade for the (K+i-1)-th term, and No otherwise.

Sample Input 1

5 3
96 98 95 100 20

Sample Output 1

Yes
No

His grade for each term is computed as follows:

3-rd term: (96 \times 98 \times 95) = 893760

4-th term: (98 \times 95 \times 100) = 931000

5-th term: (95 \times 100 \times 20) = 190000

Sample Input 2

3 2
1001 869120 1001

Sample Output 2

No

Note that the output should be No if the grade for the 3-rd term is equal to the grade for the 2-nd term.

Sample Input 3

15 7
3 1 4 1 5 9 2 6 5 3 5 8 9 7 9

Sample Output 3

Yes
Yes
No
Yes
Yes
No
Yes
Yes

Solution in Go (1.14.1) (judge verdict: Runtime Error)

package main

import (
	"fmt"
)

func main() {
	var n, k int

	fmt.Scan(&n, &k)

	a := make([]uint64, n)
	for i := 0; i < n; i++ {
		fmt.Scan(&a[i])
	}

	sum := make([]uint64, n+1)
	for i := 0; i <n ; i++ {
		if i == 0 {
			sum[i] = 1
		}
		if i >= k {
			sum[i+1] = a[i] * sum[i] / a[i+1 - (n -k)]
			continue

		}
		sum[i+1] = a[i] * sum[i]
	}


	for i := k; i <= n;i++ {
		if i == k {
			continue
		}

		if sum[i] > sum[i-1] {
			fmt.Println("Yes")
			continue
		}
		fmt.Println("No")
	}
