Valid Anagram (C)

Topics: counting, strings

Problem

bool is_anagram(const char *a, const char *b);

True if a and b contain the same bytes with the same multiplicities. Classic approach: a 256-entry count table — count up for a, down for b, and any negative count means a mismatch (after a length check).

Run: cc -std=c11 -O2 -Wall tests.c -o /tmp/a && /tmp/a
