**Abbreviation**

### Problem Statement :

You can perform the following operations on the string, a: 1.Capitalize zero or more of a's lowercase letters. 2.Delete all of the remaining lowercase letters in a. Given two strings, a and b, determine if it's possible to make a equal to b as described. If so, print YES on a new line. Otherwise, print NO. For example, given a = AbcDE and b = ABDE, in a we can convert b and delete c to match b. If a = AbcDE and b = AFDE, matching is not possible because letters may only be capitalized or discarded, not changed. Function Description Complete the function abbreviation in the editor below. It must return either YES or NO. abbreviation has the following parameter(s): a: the string to modify b: the string to match Input Format The first line contains a single integer q, the number of queries. Each of the next q pairs of lines is as follows: - The first line of each query contains a single string, a. - The second line of each query contains a single string, b. Constraints 1 <= q <= 10 1 <= |a|,|b| <= 1000 String a consists only of uppercase and lowercase English letters, ascii[A-Za-z]. String b consists only of uppercase English letters, ascii[A-Z]. Output Format For each query, print YES on a new line if it's possible to make string a equal to string b. Otherwise, print NO.

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.
