Banner From Letter Tiles

You have a box of letter tiles described by the string tiles (each character is one tile). Each tile can be used at most once.

Return true if you can spell banner exactly (characters are case-sensitive and spaces are tiles too).

Example 1

Input: banner = "ship", tiles = "hips"
Output: true

Example 2

Input: banner = "aab", tiles = "abc"
Output: false
Explanation: Only one `a` tile is available.

Constraints

  • 0 <= banner.length, tiles.length <= 10^5
  • Both strings contain printable ASCII characters.
Hint 1

Count how many of each tile you have.

Hint 2

Spend one tile per banner character and fail as soon as one runs out.
