This case will occour when all elements of A are present in B , thus no subarray can be formed
if ( $ maxSubarraySum == PHP_INT_MIN ) { echo ( " Maximum ▁ Subarray ▁ " . " Sum ▁ cant ▁ be ▁ found STRNEWLINE " ) ; } else { echo ( " The ▁ Maximum ▁ Subarray ▁ Sum ▁ = ▁ " . $ maxSubarraySum . " STRNEWLINE " ) ; } }
