WebJun 16, 2024 · Find the single non-repeating number. Example 1: Input: [2, 1, 1] Output: 2 Example 2: Input: [4, 5, 5, 2, 2] Output: 4 Problem statement: You are given an array of all positive integers. All the integers are repeated exactly twice except one. We need to find that number with a linear time complexity and using the minimum space possible. WebFor every element in the array, we will iterate the whole array and if this element is non-repeating then we will just print this element. Algorithm Run a loop for I in range 0 to n-1 Run a loop for j in range 0 to n If j becomes equal to n, then print A [i] and return. If I is not equal to j and A [i] is equal to A [j], then break from this loop. lampiran pp 5 tahun 2021 sektor pertanian
