Fix #17947
This PR fixes an index calculation bug in
topi.expand_likewhere incorrect indexing could lead to out-of-bounds access when expanding along specified axes.If
a.shape[src_dim] == 1, we useindice=0because broadcasting rules require replicating the single value across the expanded dimension, and indexing with 0 ensures correct behavior without bounds violations.
