Example 1:

Input: {"operations":["Trie","insert","search","search","startsWith","insert","search"],"args":[[],["apple"],["apple"],["app"],["app"],["app"],["app"]]}

Output: [null,null,true,false,true,null,true]

Input

arr ={"operations":["Trie","insert","search","search","startsWith","insert","search"],"args":[[],["apple"],["apple"],["app"],["app"],["app"],["app"]]}
