WebApr 10, 2024 · Initialize leftSum and rightSum as 0 and n-1 as the right pointer. Traverse the array from left to right. At each element, add the element to the leftSum and subtract it from the rightSum. If leftSum equals rightSum, return the current index as the equilibrium index. If no equilibrium index is found, return -1.
