basically i have A,B,C,D,E,F,G,H,J values in an array. The factor's letter should depend on that array. The solution which i want for the string:
$a="4ABC" or "3C" or "2A2B2C" or "ABC" ..
The result of $a should be (A * A * A * A) * (50/100) * B *(55/100) * C * (60/100). This only what i want. The solution given by holli calculates for only certain values. when i tested with some other values it directly prints the string.
