WebSum of all sub arrays in O (n) Time Objective : Given an array write an algorithm to find the sum of all the possible sub-arrays. Example: int [] a = {1, 2, 3}; Output: Possible … There are exactly n (n+1)/2 subarrays, which can be written as A [i..j] for all i and and all j≥i. The algorithm to generate all pairs is immediate (double loop) and cannot be improved. If you just need to output the pairs (i, j), space O (1) suffices. If you need to store all pairs, O (n²).

WebApproach: Click here to read about the recursive solution - Print all subarrays using recursion. Use three nested loops. Outer loops will decide the starting point of a sub-array, call it as startPoint. First inner loops will decide the group size (sub-array size). Group size starting from 1 and goes up array size. Let's call is as grps. WebDouble nested "for" loop has been used to print all the subarrays of the given array; travelling the n sized array 3 times makes the time complexity O (n^3). SPACE COMPLEXITY: O (1) Since no extra space is used, therefore space complexity is constant. So reader, we hope you understood the solution.

WebSep 8, 2024 · 1. If all entries are larger than 0 (at least 1), then each resulting sub-array has at most 4 entries. The possible results (omitting the empty result) are at most (1+2+3+4)*n many. Just iterate the start index i and in an inner loop the end index j from i+1 to i+4 and create a subList (i, j+1). This is clearly O (4*n) = O (n). WebOct 10, 2024 · To print all the subarrays (contiguous subsequences) of a given array, one requires three nested for loops.
