LANGUAGE: JAVA
CHALLENGE:
You are given an int variable k, an int array zipcodeList that has been declared and initialized , and an boolean variable duplicates.
Write some code that assigns true to duplicates if there are two adjacent elements in the array that have the same value , and that assigns false to duplicates otherwise. Use only k, zipcodeList, and duplicates.
SOLUTION:
duplicates = false;
for (k = 0; k < zipcodeList.length - 1; k++) {
if (zipcodeList[k] == zipcodeList[k+1]) duplicates = true;
}
