[ad_1] What value will var_dump show that echo will not show? You cannot echo an array if you do so it will just print data type not the data, you can use var_dump to print complete structure and data of an array. $array = array(1,2,3); echo $array; //<—-only print the data type var_dump($array) //<—–print the … Read more

[ad_1] The bitwise shift operators are the right-shift operator (>>), which moves the bits of shift_expression to the right, and the left-shift operator (<<), which moves the bits of shift_expression to the left. There are also two complex operators that can be used to assign the value directly to the value on left. These are … Read more
[ad_1] You can get the last two digits using the remainder operator, then use the digits as key of sorted: a = [311, 409, 305, 104, 301, 204, 101, 306, 313, 202, 303, 410, 401, 105, 407, 408] result = sorted(a, key=lambda x: (x % 100, x)) print(result) Output [101, 301, 401, 202, 303, 104, … Read more
