Java > Array-2 > more14 (CodingBat Solution)

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;
    
}

  2. Not sure why the formatting screwed up on previous comment...

    > public boolean more14(int[] nums) {
    > boolean result = true;
    > int zero = 0;
    > for (int i=0; i < nums.length; i++)
    > zero = (nums[i]==1) ? zero+1 : (nums[i]==4) ? zero-1 : zero;
    > result = (zero>0) ? true : false;
    > return result;
    > }
