WebThat complexity is constant. The “set” method only replaces the element at the given position, so it does not resize the underlying array nor move other elements around it. 2 Alex Eustis Software Engineer Upvoted by Marcelo De Zen , 15+ years as a software developer. and Miguel Paraz WebAug 8, 2024 · Yes, it takes O(1) time. When you initialize an array, lets say, int[] foo = new int[10] , then it will create a new array with 0s. Since int has 4 bytes, which is 32 bits, every time assign a value to one element, i.e., foo[4] = 5, it will do foo[32 x input(which is 4)] = value(5); That's why array is 0-indexed, and how they assign values in O ...
