The formula for the logarithm of the sum of exponentials is:

The formula for the logarithm of the sum of exponentials is:

logSumExp(x) = log(sum(exp(x_i))) for i = 1 to n

This is computed in a numerically stable way by subtracting the maximum value in the array before taking the exponentials:

logSumExp(x) = max(x) + log(sum(exp(x_i - max(x)))) for i = 1 to n

Given an array nums of n integers where n > 1, returns an array output such that output[i] is equal to the product of all the elements of nums except nums[i].

Given an array nums of n integers where n > 1, returns an array output such that output[i] is equal to the product of all the elements of nums except nums[i].

This method does not use division and runs in O(n) time complexity.

Value parameters

nums

An array of integers.

Attributes

Returns

An array where each element is the product of all the elements of nums except the element at the same index.
