Detailed Description

Fast inverse prefix sum.

Note

D - shared3p protection domain

Supported types - uint8 / uint16 / uint32 / uint / int8 / int16 / int32 / int

Parameters

vec	- a vector of supported type

Returns

Reverses prefixSum: subtracts the preceding element from each element of vec.

Leakage

None
