Write a function called solution that takes in an array of strings and returns a function.

returned function will return an object with only keys that exist in the input array.

const resp = solution(['apollo', 'bella', 'cinderella'])
console.log(resp({'apple': 25, 'apollo': 45, 'cindy': 84}))
// will console.log this object: {"apollo": 45}

console.log(resp({orange: 80, 'apollo': 95}))
// will console.log this object: {'apollo': 95}

console.log(resp({iron: 'man', billy: 'joel'}))
// will console.log this object: {}
