Problem Statement

You are given three integers A, B and C.
Determine whether C is not less than A and not greater than B.

Constraints

-100≤A,B,C≤100

A, B and C are all integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

If the condition is satisfied, print Yes; otherwise, print No.

Sample Input 1

1 3 2

Sample Output 1

Yes

C=2 is not less than A=1 and not greater than B=3, and thus the output should be Yes.

Sample Input 2

6 5 4

Sample Output 2

No

C=4 is less than A=6, and thus the output should be No.

Sample Input 3

2 2 2

Sample Output 3

Yes

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

'use strict'

main()

function main (input) {
  readInput()
  .then(parseInput)
  .then(calc)
}

function calc (input) {
  let a = input[0]
  let b = input[1]
  let c = input[2]
  let ok = c >= a && c <= b
  let answer = ok ? 'Yes' : 'No'
  console.log(answer)
}

function parseInput (inputRaw) {
  let input = inputRaw.split(' ').map(Number)
  return input
}

function readInput () {
  return new Promise((resolve) => {
    let inputArr = []
    process.stdin.resume()
    process.stdin.setEncoding('utf8')
    process.stdin.on('data', (chunk) => {
      inputArr.push(chunk)
    })
    process.stdin.on('end', () => {
      let input = inputArr.join('').trim()
      resolve(input)
    })
  })
}
