Hi, Everyone.
Can somebody help me to figure out why i'm getting this error:
Invalid solution: invalid collision length between StepRows
X[i] = 0590f00b220203cc410d4d9000315402698f0336fb071fb90528f30336c3
X[i+1] = 03bd590a4f5b01ca430f988b05e03c0d5ba20e8a580ed4b50a8b5101ed45

X[i] and X[i+1] can be various, but error message always appear when i'm trying to verify the solution).
Thank you.
