Problem:
Given an array of ints, return true if the number of 1's is greater than the number of 4's
more14({1, 4, 1}) → true
more14({1, 4, 1, 4}) → false
more14({1, 1}) → true
Solution:
public boolean more14(int[] nums) {
int count1 = 0;
int count4 = 0;
boolean isTrue = false;
for (int i = 0; i < nums.length; i++) {
if (nums[i] == 1)
count1++;
if (nums[i] == 4)
count4++;
}
if (count1 > count4)
isTrue = true;
return isTrue;
}
public boolean more14(int[] nums) {
ReplyDeleteboolean result = true;
int zero = 0;
for (int i=0; i0) ? true : false;
return result;
}
something is missing if this works it is legendary
