Given with an array of elements and the task is to print those numbers whose digit sum is also prime and return -1 is not such digit exists in an arrayInput: arr[]={2, 4, 3, 19, 25, 6, 11, 12, 18, 7} Output : 2, 3, 25, 11, 12, 7Here, the given output is generated as it contains those additive numbers whose sum is also prime like − 2, 3, 7 are prime but 25(2+5=7), 11(1+1=2), 12(1+2=3) are also prime whereas numbers like 19(1+9=10) are not prime.AlgorithmSTART Step 1 -> Take array of int with values Step 2 -> declare start ...
