Example 1: Input: N = 7, X = 2 Arr [] = {1, 1, 2, 2, 2, 2, 3} Output: 4 Explanation: 2 occurs 4 times in the given array. This is the best place to expand your knowledge and get prepared for your next interview. Calculate the sum of X and Y. Practice. This is the best place to expand your knowledge and get prepared for your next interview. Expected Time Complexity: O (n*m) Expected Space Compelxity: O (n) Constraints: 1 <= n <= 100. Example 1: Input: X = "25", Y = "23" Output: 48 Explanation: The. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. The solution is based on the fact that “ If a graph has no odd length cycle then it must be Bipartite, i. So the first position of the kth sequence will be occupied by the number present at index = k / (n-1)! (according to 1-based indexing). If not possible returns -1. First we store the prefix sum in a separate array so that any subarray sum can be calculated in constant time.
