- Q0p. Implplement a SnapshotArray that supports the following interface: SnapshotArray(int length) initializes an array-like data structure with the given length. Initially, each element equals 0. void set(index, val) sets the element at the given index to be equal to val. int snap() takes a snapshot of the array and returns the snap_id: the total number of times we called snap() minus 1. int get(index, snap_id) returns the value at the given index, at the time we took the snapshot with the given snap_id Example 1: Input: ["SnapshotArray","set","snap","set","get"] [[3],[0,5],[],[0,6],[0,0]] Output: [null,null,0,null,5] Explanation: SnapshotArray snapshotArr = new SnapshotArray(3); // set the length to be 3 snapshotArr.set(0,5); // Set array[0] = 5 snapshotArr.snap(); // Take a snapshot, return snap_id = 0 snapshotArr.set(0,6); snapshotArr.get(0,0); // Get the value of array[0] with snap_id = 0, return 5...A programming language permits indexing of arrays with character subscripts;for example, CHR_ARRAY[‘A’:’D’].

- Python Programming You are given an array a of length N and Q queries. Each query is described by a pair of integers, l and r. Answer each query with the following: if we take every subsequence of the elements with indices between l and r (inclusive) and write down their products, what will be the smallest missing positive integer? Input • The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows. • The first line of each test case contains two space-separated integers N and Q. The second line contains N space-separated integers a1, a2, . . ,aN. • Each of the next Q lines contains two space-separated integers, I and r, denoting the query's range. Output For each query, output the smallest missing subsequence product on a new line. Input: Output: 1 4 53 7 23254 3 23 14 35If A is a circular array of MAX elements, and rear is an index into that array, what is the formula for the index after rear? a.

- JavaScript Q3. Create a function find(arr,value) which finds a value in the given array and returns its index, or-1 if not found. The given array is: arra[10,3,20,4)Given two integer arrays prevValues and newValues. Which code copies the array prevValues into newValues? The size of both arrays is NUM_ELEMENTS. a. newValues = prevValues; b. newValues[] = prevValues[]; c. newValues[NUM_ELEMENTS] = prevValues[NUM_ELEMENTS]; d. <code>for (i = 0; i < NUM_ELEMENTS; ++i) { newValues[i] = prevValues[i]; }</code> JAVAAn array having a character subscript can be indexed using a computer language, as in CHR_ARRAY['A':'D']. In this scenario, the characters' ordinal numbers (ORDs), such as ORD('A') = 1, ORD('B') = 2, ORD('Z') = 26 and so on, are used to designate the array's elements, CHR_ARRAY['A'], CHR_ARRAY['B'], and so on. Beginning at position 500, two arrays called TEMP[1:5, -1:2] and CODE['A':'Z', 1:2] are now kept in the RAM. Furthermore, CODE outperforms TEMP in storage. Determine the locations of the following addresses: (i) TEMP[5, -1], (ii) CODE['N',2], and (iii) CODE['Z',1].
