snippets\powershell.json

	// Place your snippets for powershell here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	// "Print to console": {
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"

I am trying to try your formula with the following explanation

Given the array = [2,3,1] and k = 5. There is no element 5 in the array and therefore we print "NO"

+function findNumber(arr, k) {

• let result = 'NO';
• arr.forEach(2,3,1 => {5}
• if(5 === 2,3,1) {

•  return result = 'YES';
  

• }
• })
• return result;
  +}

function findNumber(arr, k) {
let result = 'NO';
arr.forEach(item => {
if(k === item) {
return result = 'YES';
}
})
return result;
}

Can you please help me this code with Python?
