Problem:
Given an array of ints, return true if one of the first 4 elements in the array is a 9. The array length may be less than 4.
arrayFront9({1, 2, 9, 3, 4}) → true
arrayFront9({1, 2, 3, 4, 9}) → false
arrayFront9({1, 2, 3, 4, 5}) → false
Solution:
public boolean arrayFront9(int[] nums) {
int len = nums.length;
if (len <= 4){
for (int i = 0; i < len; i++){
if (nums[i] == 9)
return true;
else;
}
} else {
for (int j = 0; j < 4; j++) {
if (nums[j] == 9)
return true;
else;
}
}
return false;
}
int count = 0;

if ( i== 9) { return true;}
if (count==4) break;
}
return false;
public String stringX(String str) {

if (str.length()<=1)

start=str.substring(0,1);

newstr+=str.charAt(i);
