Please help me rewrite this code in C language using signals and interrval timers?

char chr; short cnt; II Function to count the number of set bits in a number int count_bits(int n ) t int count =0; while (n) \{ count t=n&1; n>=1; 3 return count; 3 // Function to decode the character-integer pair void decode pair(struct data* pair) f char" decoded =( char" ) na11oc ( pa cnt +1);/ AlLocate memory for decoded string for ( int i=0;icnt;i+t) \{ decoded[i] = pair->chr; I/ Repeat the character cnt times 3 decoded[pais r>cnt]=10;/1 Add null terminator printf("(\%c, X)=% s , pair-schr, pair->ent, decoded); // Display pair and decoded string free(decoded); // Free memory
