Given an array

stringsArray of strings, and startString, endString as inputs, write a JS program to filter the strings in stringsArray starting with startString or ending with endString.

Quick Tip

You can use the array method filter() and logical operator OR ( || ).

Input

• The first line of input contains a string stringsArray
• The second line of input contains a string startString
• The third line of input contains a number endString

Output

• The output should be a single line containing an array of filtered strings

Sample Input 1

['teacher', 'friend', 'cricket', 'farmer', 'rose', 'talent', 'trainer']

t

r

Sample Output 1

[ 'teacher', 'farmer', 'talent', 'trainer' ]

Sample Input 2

['dream', 'player', 'read', 'write', 'trend']

p

d

Sample Output 2

[ 'player', 'read', 'trend' ]
