Hi. So in this question we are basically given an array of strings and a target string. we have to return the minimum no of strings we can choose from the array such that after picking some of the characters from a particular string and rearranging it we can form the target string.
Consider the example -
Input: stickers = [“with”,“example”,“science”], target = “thehat”
Output: 3
Explanation: We can use 2 “with” stickers, and 1 “example” sticker.

now the first 2 characters of the target string ie. “th” can be obtained from the string “with”, e & a of target string can be obtained from “example” and again t & h can be obtained from “with”.
Thus we can use 2 “with” stickers, and 1 “example” sticker.
