can anyone tell me where I made a mistake in this code ??
firstly I select one value of the subarray skip that array selected value of the array and compare all other elements if that element repeats in any other subarrays in checking loops then it will push that array with that element into a new array
then problem appears it may skip some value which is also repeated in subarrays
I don’t know where I made a mistake can someone help me
function same_value($multiArr, $index)
this function is selected index whome have three subarray then one by one
select value and check all other siblings arrays also
function pre($a) this function just print array at the end of the result
the algorithm i mostly use here selection and sort but I only used selection part in this program
this is array inside is subarrays
