Problem statement

You are given an integer array nums. Return the sum of the elements at even indices of the array.

Use standard zero-based indexing.

Function

sumEvenIndices(nums: int[]) → int

Examples

Example 1

nums = [4,1,7,3,2]return = 13

The even indices are 0, 2, and 4, so the sum is 4 + 7 + 2 = 13.

The source shared the rule but did not include this exact sample. FastPrep added this small example so the behavior can be checked directly.
